Abstract
Albeit rare, renal vein abnormalities on autopsy and in cases of abdominal surgery complications have been reported and should be kept in mind when performing invasive procedures, such as renal biopsy. We detected a rare renal vein abnormality on colour Doppler ultrasound before renal biopsy, thereby, avoiding a haemorrhagic complication. A 10-year-old boy presented to our department for the first time because of incidental findings of haematuria and proteinuria. We suspected chronic glomerulonephritis and scheduled an ultrasound-guided percutaneous renal biopsy. A simple screening ultrasound at the initial visit revealed no renal or vascular abnormalities. The day before the renal biopsy, we confirmed the biopsy site by performing a colour Doppler ultrasound, which showed abnormal blood flow from the lower pole of the left kidney, which was the planned puncture site; therefore, we changed the biopsy site to the right and completed the examination. Subsequent computed tomography angiography depicted two renal veins; one was the usual left renal vein draining from the kidney hilum, and the second was an accessory vein draining from the inferior pole of the left kidney and entering the inferior vena cava through the dorsal side of the aorta. Although rare, abnormalities in the renal vessels on the inferior pole of the kidney, which is the usual site of renal biopsy, are essential to rule out preoperatively by colour Doppler ultrasound, because these can cause significant bleeding during renal biopsy if not recognized.

Abstract
Objective: To analyze the ultrasonic features of tonsillar lymphoma to improve the diagnostic accuracy. Methods: The clinical, pathological and ultrasonic data of nine patients with tonsillar lymphoma confirmed by pathology at Tianjin Medical University Cancer Institute and Hospital during June 2015 and June 2022 were analyzed retrospectively, and the characteristics of their ultrasonic images were summarized. Results: All 9 cases of tonsil lymphoma were unilateral tonsil disease, including 4 cases on the left side and 5 cases on the right side. The average maximum diameter of tonsil lymphoma in 9 cases was 4.32 cm. There were 3 cases with simultaneous involvement of tonsil and cervical lymph nodes, all of which were ipsilateral lymph nodes. Gray scale ultrasound showed that the lesions were hypoechoic, with clear boundaries in 7 cases and unclear boundaries in 2 cases. The shape was full and irregular in 5 cases and oval in 4 cases. The echo was uniform in 7 cases and uneven in 2 cases. Color Doppler ultrasonography showed abundant internal blood flow signal in 1 case, a little dotted linear internal blood flow signal in 5 cases, and no obvious internal blood flow signal in 3 cases. Conclusions: The ultrasonic features of tonsillar lymphoma include hypoechoic area, clear boundary, full shape, irregular and uniform internal echo, no or low linear signal of internal blood flow. Ultrasonography is of great value in the diagnosis of this disease and can help clinical decision-making.

Abstract
Serous surface papillary borderline ovarian tumor (SSPBOT) is a distinct subtype of serous borderline ovarian tumor characterized by solid tissue deposition confined to the ovarian surface. Because SSPBOT is rare, there are few published reports on the ultrasonographic features of this condition. In this retrospective study, we investigated 12 cases of SSPBOT. Ultrasound imaging of SSPBOT showed grossly normal ovaries that were encased partially or wholly by tumor deposits that were confined to the surface, with clear demarcation between normal ovarian tissue and surrounding tumors. Color Doppler imaging demonstrated the 'fireworks sign' in all cases of SSPBOT, corresponding to an intratumoral vascular bundle originating from the ovarian vessels and supplying hierarchical branching blood flow to the surrounding tumor. No patient with ovarian high-grade serous carcinoma showed these morphological and Doppler features. In our series, the fireworks sign appeared to be a characteristic feature of SSPBOT that could facilitate correct identification of this tumor. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
Transcranial Doppler (TCD) is a repeatable, at-the-bedside, helpful tool for confirming cerebral circulatory arrest (CCA). Despite its variable accuracy, TCD is increasingly used during brain death determination, and it is considered among the optional ancillary tests in several countries. Among its limitations, the need for skilled operators with appropriate knowledge of typical CCA patterns and the lack of adequate acoustic bone windows for intracranial arteries assessment are critical. The purpose of this review is to describe how to evaluate cerebral circulatory arrest in the intensive care unit with TCD and transcranial duplex color-coded doppler (TCCD).

Abstract
Atrial septal defects (ASDs) are common in neonates. Although past studies suggest ASDs ≥ 3 mm in term neonates (TNs) are less likely to close, there is paucity of data regarding the natural history in preterm neonates (PNs), information that would inform surveillance. We sought to compare spontaneous closure rates and need for intervention for ASDs in TNs/near term (≥ 36 weeks) versus PNs (< 36 weeks). We included all TNs and PNs who underwent echocardiography at ≤ 1 month between 2010 and 2018 in our institution with an ASD ≥ 3 mm, without major congenital heart disease, and with repeat echocardiogram(s). Spontaneous resolution was defined as size diminution to < 3 mm or closure. We included 156 TNs (mean gestational age at birth 38.6 ± 1.4 weeks) and 156 PNs (29.6 ± 3.7 weeks) with a mean age at follow-up of 16 ± 19 and 15 ± 21 months, respectively (p = 0.76). Based on maximum color Doppler diameter, in TNs, ASD resolution occurred in 95% of small (3-5 mm), 87% of moderate (5.1-8 mm), and 60% of large (> 8 mm) defects; whereas, in PNs, resolution occurred in 79% of small, 76% of moderate, and 33% of large ASDs. There was a significant association between size and ASD resolution in TNs (p = 0.003), but not PNs (p = 0.17). Overall, ASD resolution rate was higher in TNs (89%) versus PNs (78%) (p = 0.009), and fewer TNs (1%) compared to PNs (7%) required ASD intervention (p = 0.02). Most ASDs identified in TNs and PNs spontaneously resolve. PNs, however, demonstrate lower ASD resolution and higher intervention rates within all size groups. These data should inform follow-up of affected neonates.

Abstract
OBJECTIVES To explore clinical value of miRNA-18a, miRNA-130a, and miRNA-92a combined with transvaginal color Doppler ultrasound (TVCDS) in the diagnosis of cervical cancer (CC). METHODS One hundred patients with pathologically confirmed CC (CC group), 100 patients with cervical epithelial neoplasia (disease group), and 100 patients with benign uterine lesions (control group) were selected. TVCDS was performed, and the levels of serum miRNA-18a, miRNA-130a, and miRNA-92a were detected. RESULTS The systolic blood velocity of the cancer group, the disease group, and the control group decreased sequentially, while the resistance index and pulsatility index increased sequentially. The serum miR-18a, miR-130a, miR-92a, and expression levels of the patients' increased sequentially. Multivariate logistic regression analysis showed that age, high-risk human papillomavirus (HR-HPV) infection, menopause, blood flow RI, serum miRNA-18a, miRNA-92a, and miRNA-130a were the influencing factors of CC. The receiver operating characteristic curve showed that the sensitivity, specificity, accuracy, and area under curve of transvaginal Doppler ultrasound in the diagnosis of CC were 86.43%, 88.01%, 84.32%, and 0.913; serum miR-18a were, respectively, 76.56, 81.30, 80.36, and 0.839; serum miR-130a were 77.88%, 76.97%, 78.32%, and 0.0.864; serum miR-92a were 71.04%, 80.39%, 80.74%, and 0.894; 90.33%, 95.14%, 91.25%, and 0.947, the area under curve of the combined detection of the 3 was greater than that of the single detection. CONCLUSIONS Serum miRNA combined with TVCDS has the advantages of it being noninvasive, and having high sensitivity and high specificity in the diagnosis of CC.

Abstract
Objective: To explore the cutting scheme and clinical application effects of ultrathin thoracodorsal artery perforator flap assisted by color Doppler ultrasound. Methods: This study was a retrospective historical control study. From February 2017 to October 2019, 20 patients who were admitted to the Third Department of Orthopedics of Xingtai General Hospital of North China Medical and Health Group (hereinafter referred to as our department), met the inclusion criteria, and underwent repair of skin and soft tissue defects of extremities with ultrathin thoracodorsal artery perforator flap designed and harvested based on the surgeon's clinical experience were selected as control group, including 16 males and 4 females, aged (37±5) years. From November 2019 to December 2022, 21 patients who were admitted to our department, met the inclusion criteria, and underwent repair of skin and soft tissue defects of extremities with ultrathin thoracodorsal artery perforator flap designed and harvested under the assistance of color Doppler ultrasound were selected as ultrasound-assisted group, including 15 males and 6 females, aged (38±6) years. After debridement, the area of skin and soft tissue defects of extremities ranged 5.0 cm×4.0 cm to 19.0 cm×8.0 cm, and the area of thoracodorsal artery perforator flaps ranged 6.0 cm×5.0 cm to 20.0 cm×9.0 cm. The wounds in flap donor sites were closed directly. For patients in ultrasound-assisted group, the time and cost required for color Doppler ultrasound examination were recorded, and the number, type, and location of thoracodorsal artery perforator vessels detected by preoperative color Doppler ultrasound were compared with those of intraoperative actual detection. The time required for complete flap harvest of patients in 2 groups was recorded. On postoperative day (POD) 1, 3, 5, 7, and 14, the blood perfusion of flaps in the 2 groups of patients was assessed using a flap perfusion assessment scale. On POD 14, flap survival of patients in 2 groups was observed, and the percentage of flap survival area was calculated. In postoperative 6 months, satisfaction of patients with the treatment outcome in the 2 groups was assessed using 5-grade Likert scale, and the satisfaction rate was calculated. Results: For patients in ultrasound-assisted group, the time required for preoperative color Doppler ultrasound examination was (10.5±2.3) min, and the cost was 120 yuan; 21 thoracodorsal artery perforator vessels were detected and marked using preoperative color Doppler ultrasound, including 8 (38.10%) type 1 perforator vessels, 10 (47.62%) type 2 perforator vessels, and 3 (14.29%) type 3 perforator vessels; the number, type, and location of thoracodorsal artery perforator vessels detected preoperatively were consistent with those detected intraoperatively. The time required for complete flap harvest of patients in ultrasound-assisted group was (41±10) min, which was significantly shorter than (63±12) min in control group (t=6.32, P<0.05). On POD 1, 3, 5, 7, and 14, the blood perfusion scores of flaps of patients in ultrasound-assisted group were significantly better than those in control group (with t values of 6.67, 7.48, 8.03, 8.75, and 7.99, respectively P<0.05). On POD 14, only one patient in ultrasound-assisted group had partial flap necrosis and 6 patients in control group had complete or partial necrosis of the flap; the percentage of flap survival area of patients in ultrasound-assisted group was (99±8)%, which was significantly higher than (87±8)% in control group (t=4.57, P<0.05). In postoperative 6 months, there was no significant difference in the satisfaction rate of patients with the treatment outcome between the two groups (P>0.05). Conclusions: Preoperative color Doppler ultrasound is highly accurate in detecting the number, type, and location of perforator vessels. The cutting scheme of ultrathin thoracodorsal artery perforator flaps can be designed according to the different types of perforator vessels, with shorted flap cutting time and improved flap survival rate.

Abstract
OBJECTIVE To evaluate the utility of color Doppler ultrasonography in assessing infantile hemangioma response to treatment with oral propranolol. METHODS A prospective study was conducted between January, 2016 and December, 2022, wherein children with symptomatic (ulceration, bleeding, pain and scarring) infantile hemangioma were given oral propranol (2 mg/kg per day in three divided doses) as outpatient therapy. The clinical response was assessed three months post-initiation of treatment (intermediate clinical response) and three months post-completion of treatment (final clinical response, FCR). The primary outcome measurement was a clinical and radiological response (resistivity index (RI), pulsatility index (PI) and peak systolic velocity) to treatment. The secondary outcomes assessed were the complications related to treatment. RESULTS Out of 601 patients who were started on propranolol, 99 developed severe adverse effects and were excluded from analysis. At FCR assessment, out of 502 participants, 64.3% (n = 323) showed excellent response, 17.7% (n = 89) showed partial, and 17.9% (n = 90) were non-responders. A significant increase in RI and PI values was noted in all children following propranolol treatment for six months. An increase > 7.5% in RI could identify responders with 92% sensitivity, 91% specificity and area under the curve (AUC) of 0.963. An increase of > 11.5% in PI could identify responders with 86% sensitivity, 91% specificity and AUC of 0.896. Patients initially showing no response but later becoming excellent responders had significantly higher RI and PI values. CONCLUSIONS Color Doppler ultrasonography is a valuable tool in predicting the treatment outcome of infantile hemangioma using propranolol.

Abstract
PURPOSE In the case of ischemic optic neuropathy (ION) or retinal artery occlusion (RAO), distinguishing arteritic from non-arteritic can limit or prevent irreversible bilateral blindness. Here, the utility of color Doppler ultrasonography (CDUS) in diagnosing giant cell arteritis (GCA) was evaluated. METHODS In this retrospective analysis, a total of 38 cases diagnosed with ION or RAO were included, that presented to our department in the years 2018 up to 2021 and underwent both CDUS and temporal artery biopsy (TAB). The evaluation is based on TAB as reference standard. RESULTS CDUS resulted in a sensitivity of 65.0% and a specificity of 100% (when excluding two inconclusive assessments). Therefore, when limiting TAB to only suspected cases with negative or unclear CDUS findings, the sensitivity and the specificity would remain unchanged at 100%, while reducing the need for TAB by 42.1%. CONCLUSION Overall, the data suggest the implementation of a stepwise diagnostic algorithm to confirm or rule out GCA, in which the CDUS plays a key role, thus omitting the requirement for TAB in many cases.

Abstract
OBJECTIVES Our institution introduced universal vasa previa (VP) screening utilizing transabdominal ultrasound with color Doppler for all pregnancies at the second trimester anatomy scan. Our study sought to describe the clinical impact of this intervention. METHODS Radiology records from the 12 months pre- and post-intervention were queried for "vasa previa." Records included for analysis were those with a first-time diagnosis or discussion of VP at the anatomy scan. Cases were categorized by outcome: (Group 1) True VP, with subgroups A, unresolved by time of delivery and B, resolved by delivery; (Group 2) False positives; (Group 3) Possible VP without definitive diagnosis; and (Group 4) VP ruled out, for example, "no features of VP." Group size was expressed as a percentage of total anatomy scans during pre- or post-intervention periods respectively. Absolute and relative percent change were calculated for each group. RESULTS In the pre-intervention period, 1 case (0.36% of total scans) was categorized in Group 1A, 1 case (0.36%) in Group 3, and 7 cases (2.53%) in Group 4. In the post-intervention period, 2 cases (0.30%) were in Group 1A, 4 cases (0.61%) in Group 1B, 2 cases (0.30%) in Group 2, 1 case (0.15%) in Group 3, and 7 cases (1.06%) in Group 4. There was a +153% relative change in true positives, from 0.36 to 0.91%. CONCLUSIONS Universal color Doppler screening may have increased detection (sensitivity) while simultaneously increasing false positives (decreased specificity). While decreasing sensitivity is not ideal, this is acceptable given the potential catastrophic outcome of a missed VP.

Abstract
Mitral valve cleft (MVC) is the most common cause of congenital mitral regurgitation (MR). MVC may be located on the anterior or posterior leaflets. We evaluated children with moderate-to-severe MR using 3D transthoracic echocardiography (3DTTE) to diagnose MVC and determine the location, shape and size of MVC. Twenty-one patients under 18 years of age with moderate-to-severe MR without symptoms who were suspected of having MVC were included in the study. The patients' history and clinical data were obtained from the medical records. 2D and 3D imaging were performed with a high-quality machine (EPIQ CVx). A vena contracta (VC) of colour Doppler regurgitated jet 3-7 and ≥ 7 mm defined moderate-to-severe regurgitation. An isolated anterior leaflet cleft (ALC) was detected in four patients, an isolated posterior leaflet cleft (PLC) in 12 patients, and both an ALC and PLC in five patients. VC was larger in patients with ALCs than PLCs (8.85 mm vs. 6.64 mm). Global LV longitudinal strain was better in the ALC group than in the PLC and both-posterior-and anterior MVC groups (- 24.7, - 24.3, and - 24%, respectively). Global circumferential strain was better in the ALC group (- 28.9%) and reduced in the bi-leaflet MVC group (- 28.6%). 3DTTE for visualisation of the MV can be successfully implemented in children and should be proposed during follow-up. AMVC and bi-leaflet MVC results in severe regurgitation and bi-leaflet MVC may be the reason for systolic dysfunction determined before clinically proven symptoms in the future.

Abstract
Transthoracic echocardiography is used routinely during the follow-up after heart transplant surgery to screen possible complications and adverse events such as rejection. It often results in incidental findings that bring diagnostic challenges for sonographers. This E-challenge shows a Doppler flow abnormality associated with a rare cardiovascular diagnosis. Its physiopathology and its association with echocardiography findings are reviewed.

Abstract
This paper proposes a novel thyroid examination technique based on five-dimensional (5D) synchronous reconstruction of ultrasound data. The raw temporal sequences are reconstructed into 3D volumetric data reflecting anatomical structure. Triplanar visualization from three orthogonal planes is realized to provide a systematic inspection of the entire gland. Color Doppler imaging is integrated into each triplanar slice to map vascularity changes. This multi-modal fusion enables synchronous display of structural, functional, and blood flow information in the reconstructed 5D space. Compared to conventional scanning, this technique offers the benefits of flexible offline diagnosis, reduced dependency on scanning, enhanced intuitive interpretation, and comprehensive multi-aspect evaluation. By minimizing oversight errors, it could improve diagnostic accuracy, especially for novice practitioners. The proposed 5D fusion method allows rapid and precise localization of lesions for early detection. Future work will explore integration with biochemical markers to further improve diagnostic precision. The technique has considerable clinical value for advancing thyroid examination.

Abstract
OBJECTIVE To evaluate the value of multimodal ultrasonography (US) in a rat experimental torsion model after 6 h of torsion with different degrees. METHODS Twenty-one male rats were divided into three groups. Left testes of the rats were twisted around their vascular pedicle 360 degrees in group 1, 720 degrees in group 2, and 1080 degrees in group 3 and intact right testes of the rats were accepted as control group. Grey-scale US, superb microvascular imaging (SMI), colour Doppler ultrasonography (CDUS), strain elastography (SE), and two-dimensional (2-D) shear wave elastography (SWE) examinations were applied 6 h after torsion procedure and testes were removed for pathological evaluation. RESULTS Short-axis dimensions and volumes of the torsion side were higher than control testes. Lengths of the testes in the 3rd torsion group were smaller than the testes in groups 1 and 2 (P < 0.002). SMI was better than CDUS in recognizing blood flow in testicular tissue. Strain ratios were higher in group 1 and decreased with the increasing torsion degree. Emean and standard deviation (SD) measurements increased in the torsion side. Pathologically the mean testicular damage scores were statistically significant between torsion and control testes in all groups. CONCLUSION Our results showed that short-axis and volume measurements, SMI, 2D-SWE, and SE are effective in the evaluation and diagnosis of testicular torsion (TT). ADVANCES IN KNOWLEDGE Evaluation of affected testis and intact testis with multiparametric US in late presenting TT cases is more reliable than being dependent on a single sonographic modality.

Abstract
Vector flow imaging (VFI) is an innovative ultrasound flow measurement technology. Compared with the traditional color Doppler and spectral Doppler, VFI has the advantages of independence of angle correction and direct acquisition of real-time amplitude and direction of flow. Transverse oscillation (TO) method is one of the effective methods for vector flow imaging. However, a complete and detailed algorithm validation process based on commercial ultrasound machines is still lacking due to more complex convex probes. This study starts with introducing the imaging process and principle of transverse oscillation vector flow technique, and calculates the error between the set velocity value and the measured velocity value through the simulation experiment, and verifies the error between the set velocity value and the measured velocity value through the Doppler flow phantom experiment. Among them, the velocity value measured by the TO vector flow technique in the simulation experiment is 0.48 m/s and the preset value is 0.50 m/s, the error between them is -4%. The velocity values are 8.33, 11.14, 14.44 and 16.67 cm/s measured by the Doppler flow phantom experiment, the actual velocity values are 7.97, 10.78, 14.06 and 17.34 cm/s, the errors between them are all within ±5%. Both experiments verify the feasibility of using vector flow technique on abdominal convex probe.

Abstract
Objective To investigate the clinical application of high-frequency color Doppler ultrasound (HFCDU) in detecting perforators in the deep adipose layers for harvesting super-thin anterolateral thigh flap (ALTF). Methods Between August 2019 and January 2023, 45 patients (46 sides) with skin and soft tissue defects in the foot and ankle were treated, including 29 males and 16 females, aged from 22 to 62 years, with an average of 46.7 years. The body mass index ranged from 19.6 to 36.2 kg/m 2, with an average of 23.62 kg/m 2. The causes of injury included traffic accident injury in 15 cases, heavy object crush injury in 20 cases, mechanical injury in 8 cases, heat crush injury in 1 case, and chronic infection in 1 case. There were 20 cases on the left side, 24 cases on the right side, and 1 case on both sides. After thorough debridement, the wound size ranged from 5 cm×4 cm to 17 cm×11 cm. All patients underwent free super-thin ALTF transplantation repair. HFCDU was used to detect the location of the perforators piercing the deep and superficial fascia, as well as the direction and branches of the perforators within the deep adipose layers before operation. According to the preoperative HFCDU findings, the dimensions of the super-thin ALTF ranged from 6 cm×4 cm to 18 cm×12 cm. The donor sites of the flaps were directly sutured. Results A total of 55 perforators were detected by HFCDU before operation, but 1 was not found during operation. During operation, a total of 56 perforators were found, and 2 perforators were not detected by HFCDU. The positive predictive value of HFCDU for identifying perforator vessels was 98.2%, and the sensitivity was 96.4%. Among the 54 perforators accurately located by HFCDU, the orientation of the perforators in the deep adipose layers was confirmed during operation. There were 21 perforators (38.9%) traveled laterally and inferiorly, 12 (22.2%) traveled medially and inferiorly, 14 (25.9%) traveled laterally and superiorly, 5 (9.3%) traveled medially and superiorly, and 2 (3.7%) ran almost vertically to the body surface. Among the 54 perforators accurately located by HFCDU, 35 were identified as type 1 perforators and 12 as type 2 perforators (HFCDU misidentified 7 type 2 perforators as type 1 perforators). The sensitivity of HFCDU in identifying type 1 perforators was 100%, with a positive predictive value of 83.3%. For type 2 perforators, the sensitivity was 63.2%, and the positive predictive value was 100%. The surgeries were successfully completed. The super-thin ALTF had a thickness ranging from 2 to 6 mm, with an average of 3.56 mm. All super-thin ALTF survived, however, 1 flap experienced a venous crisis at 1 day after operation, but it survived after emergency exploration and re-anastomosis of the veins; 1 flap developed venous crisis at 3 days after operation but survived after bleeding with several small incisions; 3 flaps had necrosis at the distal edge of the epidermis, which healed after undergoing dressing changes. All 45 patients were followed up 6-18 months (mean, 13.6 months). Three flaps required secondary defatting procedures, while the rest had the appropriate thickness, and the overall appearance was satisfactory. Conclusion Preoperative application of HFCDU to detect the perforator in the deep adipose layers can improve the success and safety of the procedure by facilitating the harvest of super-thin ALTF.

Abstract
OBJECTIVE This study aimed to identify the sonographic features of pathologically confirmed onychopapilloma cases. METHODS High-frequency up to 24 MHz and ultra-high frequency-ultrasound up to 71 MHz examinations were performed and correlated with their clinical and pathologic presentations. RESULTS Twenty-two cases met the criteria. Clinical presentations revealed longitudinal erythronychia in 63.3% of cases. The ultrasound examinations identified a hypoechoic band in the nail bed (86.3%), nail plate abnormalities including upward displacement (68.2%) and thickening (68.1%), focal hyperechoic focal spots on the nail plate (50%) and irregularities of the ventral plate (33.3%). Color Doppler imaging showed no hypervascularity of the nail bed in all studies. These findings correlate with histological characteristics of onychopapilloma, including nail bed acanthosis, papillomatosis, and layered hyperkeratosis. Recurrence occurred in two cases after surgery, with tumors showing proximal extension in the matrix region on ultrasound not evident during clinical examination. CONCLUSION High-frequency and ultra-high-frequency can provide anatomical information in onychopapilloma that could enhance understanding and management.

Abstract
Erectile dysfunction (ED) is common in type 2 diabetes mellitus (T2DM). ED is considered the earliest marker of widespread endothelial dysfunction. Color Doppler ultrasonography (CDUS) of the penis is a valuable tool in identifying vasculogenic ED and may predict coronary vascular disease. In Bangladesh, no study has evaluated CDUS of the penis in such patients. This study assessed the penile CDUS characteristics of adult patients with T2DM having ED. This cross-sectional study was conducted from January to December 2021 at a specialized diabetes hospital in Cumilla, Bangladesh. The baseline velocities of the right and the left cavernosal arteries were measured at the penile base. Arterial insufficiency was defined as a peak systolic velocity (PSV) value <25 cm/s and venous insufficiency was described as an end-diastolic velocity (EDV) >5 cm/s at the end of the examination. Eighty-seven subjects were evaluated; the mean age was 44.2±9.2 years, mean duration of DM was 7.9±2.8 years; of them, 31.0% were smokers, 75.9% obese, 92.0% central obese, 69.0% hypertensive, 96.6% dyslipidemic and 51.7% with low testosterone. The mean HbA1c was 9.3±1.9%; DM was uncontrolled in 89.7% of the study subjects. Penile vasculopathy was found in 21.8% (17.2% had arterial insufficiency, 2.3% had a venous leak, and 2.3% had arterial insufficiency with a venous leak). There were no statistical differences between the two groups, with and without penile vasculopathy, except for diastolic blood pressure, which was higher in the vasculopathy group. CDUS may be incorporated into the tools for evaluating diabetic ED to direct specific management.

METHODS In this pilot study, the new ultrasound device TE Air from Mindray was used to examine the hepatic and renal vessels of healthy volunteers for first impressions. The probe has a sector transducer with a frequency range of 1.8-4.5 MHz. The B-mode and color-coded doppler sonography (CCDS) scanning methods were used. A high-end device from the same company (Resona 9, Mindray) was used as a reference. The results were evaluated using an image rating scale ranging from 0 to 5, with 0 indicating not assessable and 5 indicating without limitations. RESULTS Altogether, 61 participants (n = 34 female [55.7%], n = 27 male [44.3%]), age range 18-83 years, mean age 37.9±16.5 years) could be adequately studied using TE AIR and the high-end device. With one exception, the image quality score for TE Air never fell below 3 and had a mean/median scored of 4.97/5.00 for the B-mode, 4.92/5.00 for the color flow (CF) mode, and 4.89/5.00 for the pulse wave (PW) mode of the hepatic vein, 4.90/5.00 for the portal vein, 4.11/4.00 for the hepatic artery, and 4.57/5.00 for the renal segmental artery. A significant difference in the assessment of flow measurement of the hepatic artery and renal segmental arteries was found between TE AIR and the high-end device. CONCLUSIONS TE Air represents a new dimension in point-of-care ultrasound via wireless handheld devices. Especially, its flow measurement ability offers a relevant advantage over other available handheld models. TE Air provides a formally sufficient image quality in terms of diagnostic significance.

Abstract
Hidradenitis suppurativa (HS) is a devasting autoimmune cutaneous disease that affects the hair follicles and can clinically present palpable nodules, abscesses, and tunnels (fistulas), usually in the intertriginous regions. It has been widely reported that color Doppler ultrasound can detect subclinical abnormalities and stage the severity of the disease more accurately. Nevertheless, the ultrasound diagnostic criteria were reported with 15 MHz 10 years ago, and now it is possible to detect early anatomical abnormalities in HS using 70 MHz. Thus, an update of the ultrasonographic diagnostic criteria is needed. The most widely used sonographic staging of severity of HS (SOS-HS) includes the number of affected regions, besides counting the number of key lesions like pseudocysts, fluid collections, and tunnels; however, the total number of affected regions may fit better in an activity scoring. Furthermore, a high number of tunnels or communicated tunnels can complicate the management and may indicate an even more urgent treatment, which should be considered in the severity classification. To date, no hidradenitis scoring of activity has been reported in the literature, making it difficult to track the degree of inflammation under treatment objectively. Therefore, two new scorings are proposed. The first is an updated sonographic scoring of severity called modified SOS-HS (mSOS-HS), and the second is an activity ultrasound scoring of HS called US-HSA. Both staging systems can provide better anatomical information for discriminating the categories and, therefore, selecting more appropriate treatments and supporting research and clinical trials by giving more objective anatomical tools in real-world settings.

Abstract
OBJECTIVE In this study, the color ultrasound indicators of carotid atherosclerosis (CAS) intima-media thickness (IMT) and atherosclerotic plaque (AP) were retrospectively analyzed for the prediction of CHD with the help of compressed speckle denoising. PATIENTS AND METHODS A total of 248 patients with suspected coronary atherosclerosis admitted to the Department of Cardiovascular Medicine of The First Affiliated Hospital of Harbin Medical University from August 2020 to January 2022 were retrospectively recruited as research subjects. RESULTS The plaque detection rate (71.83%), IMT (1.26 ± 0.75) mm, and plaque index (PI) (2.31 ± 0.95) in the Obs group were greatly higher. The IMT and PI values in the patients with two CALs were superior to those in patients with a single CAL, and the IMT and PI values in the patients with three CALs were higher than those in patients with two CALs, illustrating considerable differences between the two groups (p < 0.05). The predictive sensitivity of IMT combined with AP was higher than that of IMT and AP (p < 0.05), and the predictive specificity of AP results was markedly inferior to that of IMT and IMT combined with AP (p < 0.05). CONCLUSIONS The ultrasound examination of CAS had obvious predictive value for the occurrence and disease severity of CHD. The higher the IMT and AP, the higher the incidence and severity of CAD.

Abstract
The CME review is intended to explain and discuss the clinical value of lung ultrasound but also to enable a pragmatically oriented approach by analyzing the clinical aspect. This includes knowledge of the pre-test probability, the acuteness of the disease, the current clinical situation, detection and/or characterization, initial diagnosis or follow up assessment and the peculiarities of exclusion diagnosis. Diseases of the pleura and lungs are described using these criteria with their direct and indirect sonographic signs and the specific clinical significance of ultrasound findings. The importance and criteria of conventional B-mode, color Doppler ultrasound with or without spectral analysis of the Doppler signal and contrast-enhanced ultrasound are discussed as well.

Abstract
OBJECTIVE To develop deep learning (DL) prediction models using transvaginal ultrasound (TVS), transabdominal ultrasound (TAS), and color Doppler flow imaging (CDFI) of TVS (CDFI_TVS) to automatically predict benign or malignant ovarian tumors. METHODS This retrospective study included women with ovarian tumors who underwent ultrasound between August 2018 and October 2022. Histopathological analysis was used as a reference standard. The dataset was preprocessed by clipping, flipping, and rotating images to generate a larger, more complicated, and diverse dataset to improve accuracy and generalizability. The dataset was then divided into training (80%) and test (20%) sets. The weights of the models, modified from the residual network (ResNet) with the TVS, TAS, and CDFI_TVS images (hereafter, referred to as DLTVS , DLTAS , and DLCDFI_TVS , respectively) were developed. The area under the receiver operating characteristic curve (AUC) analysis in the test set was used to compare the predictive value of DL for malignancy. RESULTS A total of 2340 images from 1350 women with adnexal masses were included. DLTVS had an AUC of 0.95 (95% CI: 0.93-0.97) for classifying malignant and benign ovarian tumors, comparable with that of DLTAS (AUC, 0.95; 95% CI: 0.91-0.98; p = 0.96) and DLCDFI_TVS (AUC, 0.88; 95% CI: 0.84-0.93; p = 0.02). Decision curve analysis indicated that DLTVS performed better than DLTAS and DLCDFI_TVS . CONCLUSION We developed DL models based on TVS, TAS, and CDFI_TVS on ultrasound images to predict benign and malignant ovarian tumors with high diagnostic performance. The DLTVS model had the best prediction compared with the DLTAS and DLCDFI_TVS models.

Abstract
PURPOSE To study the orbital perfusion parameters of ophthalmic artery (OA) and central retinal artery (CRA) in inactive TED and the changes following surgical decompression. METHODS Non-randomised clinical trial. 24 inactive moderate-to-severe TED orbits of 24 euthyroid cases underwent surgical decompression and examined again at 3 months. The peak systolic velocity (PSV), end-diastolic velocity (EDV), and resistivity index (RI) of OA and CRA were evaluated using colour doppler imaging and normative database was established using 18 healthy controls. RESULTS The mean age was 39.38 ± 12.56 years and male: female ratio was 1: 1.18. Intraocular pressure was higher, and CRA-PSV, CRA-RI, OA-PSV, and OA-EDV were lower in TED in comparison to heathy orbits. The CRA-PSV, CRA-EDV, OA-PSV, and OA-EDV negatively correlated with proptosis and duration of thyroid disease. The area under curve of OA-PSV (95% CI:0.964-1.000, p < 0.001) and OA-EDV (95% CI:0.699-0.905, p < 0.001) helped in differentiating TED orbits from HC, and in predicting the severity of disease. Post decompression, CRA-PSV, CRA-EDV, OA-PSV, and OA-EDV improved, with decrease in CRA-RI and OA-RI in both lipogenic and MO. CONCLUSIONS The orbital perfusion is reduced in inactive TED. The changes in OA flow velocities can help in differentiating inactive TED from healthy orbits and progression of TED. Sequential orbital CDI of OA and CRA can serve as an objective tool for case selection and monitoring response to surgical decompression.

Abstract
This study evaluated the clinical value of color Doppler ultrasound-guided percutaneous nephrolithotomy (PCNL) in avoiding bleeding caused by punctured blood vessels. Herein, we retrospectively included patients who underwent color Doppler ultrasound-guided PCNL or PCNL using the conventional channel technique from August 2018 to August 2022. The clinical characteristics of patients during surgery, complications, and hospital stay were recorded and compared. Overall, 228 patients were enrolled, with 126 patients (age, 47.6 ± 13.2 years; men: 57.14%) in the color Doppler ultrasound-guided PCNL group and 102 patients (age, 46.6 ± 12.3 years) in the B-mode ultrasound-guided puncture group. The total operation time (63.5 ± 15.5 vs. 61.3 ± 16.3 min, p = .5236) and stone clearance rate (86.50% vs. 83.33%, p = .7139) were similar between the two groups. However, the puncture time for the color Doppler ultrasound-guided PCNL group was longer than that for the B-mode ultrasound-guided puncture group (5.1 ± 2.3 vs. 2.6 ± 1.6 min, p = .0019). Moreover, the length of postoperative hospital stay in the color Doppler ultrasound-guided PCNL group reduced significantly by ∼1 day compared with that in the B-mode ultrasound-guided puncture group (4.5 ± 1.6 vs. 5.6 ± 2.1 days, p = .0087). The blood transfusion rate (1.58% vs. 4.9%, p = .0399), sedation-related adverse event rate (0.79% vs. 2.9%, p = .0332), perineal hematoma incidence (0% vs. 2.94%, p < .0001), and serum decreased hemoglobin levels (12.2 ± 9.7 vs. 23.5 ± 10.1 g/L, p < .001) after color Doppler ultrasound-guided PCNL were significantly lower than those after B-mode ultrasound-guided puncture. The stone clearance rate was similar between the two groups, with a similar operation time. Moreover, color Doppler ultrasound-guided PCNL shortened the postoperative hospital stay and decreased Hb levels, blood transfusion rate, and perineal hematoma incidence.

Abstract
We aimed to evaluate the impact of corpus luteum (CL) and uterine characteristics accessed by B-mode and Color-Doppler ultrasonography in recipient mares at the time of embryo transfer (ET) on pregnancy outcomes. Recipient mares (n = 110), between days 3-9 after spontaneous ovulation, received a fresh embryo. Immediately before ET, the reproductive system was assessed by transrectal palpation for the following parameters: uterine tone (0-3), CL echogenicity (0-6), CL type (homogeneous, trabecular or anechoic center), luteal area (cm2), uterine echogenicity (0-3), uterine edema (0-3), luteal blood perfusion (0-100%) and uterine blood perfusion (1-4). Additionally, a blood sample was collected by puncture of the jugular vein for plasma P4 dosage. Retrospectively, recipients were classified according to the luteal area (small [≤ 6 cm2] or large [> 6 cm2]), luteal blood perfusion (low [≤ 55%] or high [> 55%]), and plasma concentration of P4 (low ≤ 9.98 ng/mL or high > 9.98 ng/mL). Pregnancy diagnosis was performed at 12 and 30 days of gestation. Luteal blood perfusion was significantly higher (P = 0.04) in pregnant recipients (n = 83) than in non-pregnant recipients (n = 27). Overall P/ET was higher (P ≤ 0.02) in mares with high luteal blood perfusion and high P4. Luteal blood perfusion was the most adequate significant (P = 0.01) predictor of pregnancy compared with the luteal area and plasma P4 concentration. Only luteal blood perfusion showed a linear (P = 0.03) and cubic (P = 0.004) effect on P/ET. In conclusion, CL blood perfusion determined by color-Doppler can be used in real-time to select recipients with the greatest chance of maintaining pregnancy in equine ET programs.

Abstract
BACKGROUND Identifying relevant perforators is crucial in planning a deep inferior epigastric perforator (DIEP) flap. Color Doppler ultrasonography (CDU) has gained popularity for localizing perforators; however, current evidence on its efficiency is still inconclusive. This study aimed to compare the efficiency of CDU with that of computed tomography angiography (CTA) in localizing and selecting the relevant perforators. METHODS In this randomized controlled trial, 60 patients undergoing DIEP flap breast reconstruction (uni- or bilateral) were randomly assigned to the CDU group (i.e., CDU was performed to map and select the relevant perforators preoperatively) or the CTA+CDU group (i.e., mapping was based on CTA and supplemented by CDU). CDU was performed by the same surgeon with a well-defined sonography experience from our previous study. The reference XY coordinates of the dissected perforators were measured intraoperatively, and deviations from preoperatively deducted coordinates were calculated (ΔCDU or ΔCTA+CDU). The flaps were categorized according to the number of dissected perforators, and adherence to the preoperative strategy was evaluated. RESULTS Overall, 22 patients (30 flaps) in the CTA+CDU group and 27 (39 flaps) patients in the CDU group were evaluated. The average ΔCDU (0.6 cm) was significantly lower than the average ΔCTA+CDU (1.0 cm) (p < 0.001). Adherence to the mapping-based dissection strategy was higher in the CDU group; however, the difference was insignificant (p = 0.092). CONCLUSION CDU is not inferior to CTA + CDU in localizing and selecting relevant DIEA perforators. Therefore, CDU mapping is a possible complementary or substitute modality for CTA mapping.

Abstract
To compare changes in ophthalmic artery (OA) and its branches in diabetics with and without diabetic retinopathy (DR) using color duplex imaging (CDI), and to correlate these changes with the disease variables. 60 eyes of 60 diabetic patients were enrolled, divided into 3 groups: without DR (Group A), with Non-Proliferative DR (Group B) and with Proliferative DR (PDR) (Group C). Laboratory testing including HbA1c was done. Patients underwent CDI, by which OA, Central Retinal Artery (CRA) and Ciliary Arteries were identified; for each of them we measured Peak systolic velocity (PSV), End Diastolic velocity (EDV) and Resistivity Index (RI). Results were compared to clinical, laboratory and fundus examination. OA EDV was significantly lower and OA RI was found to be significantly higher in Group C (p = 0.027 and 0.025 respectively). CRA PSV and EDV were significantly lower in Group C (p = 0.017 and 0.001 respectively). PCA RI was significantly higher in Group C (p = 0.008). HbA1c was negatively correlated with CRA PSV (p = 0.041), also it was negatively correlated with CRA EDV (p = 0.0001), as well as with PCA EDV (p = 0.002). There was direct significant correlation between HbA1c and PCA RI (p = 0.012). Duration since diagnosis was negatively correlated with CRA EDV (p = 0.004). Multivariate linear regression showed that DR is an independent predictor for low OA EDV, high OA RI, low CRA EDV and high PCA RI. DR is an independent risk factor for orbital and ocular vessels flow alteration, thus can be used as a prognostic tool in diabetic patients. CDI can be reliably used in diabetics to predict early changes or progression of DR.

Abstract
Ultrasonography of intracranial arteries is a non-invasive and highly efficient method for the diagnosis and follow-up of patients with cerebrovascular diseases, also in the bedside setting of the critically ill. For reliable assessment and interpretation of sonographic findings, the technique requires - apart from dedicated anatomic and pathophysiological knowledge of cerebral arteries and their hemodynamics - the comprehension of alternative imaging modalities such as CT or MR angiography. This article reviews the transcranial color-coded duplex sonographic (TCCS) examination technique including the transcranial Doppler sonography (TCD) for a standardized ultrasound assessment of the intracranial arteries and typical pathological cases. As a complementary tool, transorbital ultrasound for the assessment of the optic nerve sheath diameter and adjacent structures is also described in this article.

Abstract
AIM Adenomyoma is an exceptionally rare hamartoma in the small intestine. Few data have been reported on the features of this rare disease. The aim of this study was to describe the ultrasound (US) characteristics of small intestinal adenomyomas. Material and methods: This retrospective study analyzed the clinical features and US data of 15 pediatric patients diagnosed as small intestinal adenomyomas in the age range between 1 day to 12 years in our hospital during 2014-2021. RESULTS The clinical manifestations of all the small intestinal adenomyomas were abdominal pain, vomiting or/and hemafecia. The small intestinal adenomyoma usually acted as the lead point of secondary intussusception. They were identified in the ileum (n=11), jejunum (n=2), and Meckel's diverticulum (n=2). The diagnostic accuracy (the concordance rate between US diagnosis and pathological diagnosis) of small intestinal adenomyoma was 73.3%. The small intestinal adenomyoma had approximately 1.0-3.0 cm, were typically located in the submucosal region, had the basal part wide and without a pedicle, and its boundaries were clear. The mass protruded into the intestinal cavity, and showed oval hypoechoic polycystic echo nodules, containing multiple small quasi-circular or irregular cysts of different sizes surrounded by solid hypoechoic mosaic areas. The color Doppler US showed in the solid hypoechoic areas of the mass abundant or sparse blood flow signals.Conclusions The US findings of small intestinal adenomyomas in children are characteristic, and US is valuable in the identification of intestinal adenomyomas in children.

Abstract
BACKGROUND Detection of activity in morphea is paramount for adequately managing the disease. Subclinical ultrasound involvement on inactive lesions or healthy skin areas adjacent to morphea has not been described to date. OBJECTIVES The study aimed to detect morphea's subclinical activity by Color Doppler ultrasound not identified with the clinical scorings. MATERIALS & METHODS This cross-sectional retrospective study was done from January 2014 to July 2019 in patients with a clinicopathological diagnosis of morphea. The modified Localized Scleroderma Skin Severity Index (mLoSSI) and The Ultrasound Morphea Activity Score (US-MAS) were used to correlate clinical and subclinical activity. RESULTS A total of 36 patients met the inclusion criteria. 54% of cases presented subclinical activity in areas adjacent to the clinically active lesion, 23% in nonadjacent regions, and 23% demonstrated activity at a clinically inactive lesion site.100% of patients with morphea "en coup de sabre" involving the frontal region of the face concomitantly presented both subclinical activities of morphea on the frontal facial region and the scalp following the same axis.A positive relationship was observed between the degree of clinical activity measured by mLoSSI and US-MAS scoring.The main limitations of our study were the low number of patients and the inability to detect alterations < 0.1 mm. CONCLUSIONS Subclinical activity is frequent in morphea, can extend beyond the lesional areas, including apparently noninvolved adjacent and distant corporal regions, and can be detected by color Doppler ultrasound.

Abstract
OBJECTIVE To explore a method for early diagnosis of knee osteoarthritis (OA) by comparing vascular morphology and hemodynamic parameters between healthy controls and patients, and explore the effects of age on the blood flow of healthy subjects. MATERIAL AND METHODS 80 healthy subjects and 106 patients with knee OA were recruited. Color Doppler ultrasound was used to measure the vascular morphology and hemodynamic parameters of 11 blood vessels around the knee joint. A general linear model was used to analyze the difference of blood flow parameters between healthy controls and patients, and to explore the effects of sex and age on the blood flow of healthy subjects. RESULTS Age has no significant effect on the vessel diameter of healthy subjects, and it only affect the blood flow velocity (P < 0.05) and blood flow volume (P <0.0083) of a few blood vessels. There was no significant difference in vascular morphological parameter between healthy controls, patients with mild OA and moderate/severe OA, but there was significant difference in vascular hemodynamic parameters (P < 0.0167). Specifically, in the early stage of knee OA, hemodynamic parameters of main arteries in patients did not change significantly, but those of branch vessels changed significantly (P < 0.0167). With the development of knee OA, the difference of hemodynamic parameters of branch vessels in patients increased gradually. CONCLUSION Hemodynamic parameters of branch vessels around the knee joint have changed significantly in the early stage of knee OA, which can be treated as an important index to screening the early patients.

Abstract
OBJECTIVES We evaluated sensitivity to change and discriminative abilities of vascular US scores in disease monitoring in the follow-up of a prospective cohort of new-onset cranial and large-vessel (LV) GCA patients. METHODS Baseline and follow-up (8 weeks, 24 weeks and 15 months) US of temporal arteries (TA), carotid and axillary arteries (LV) included assessment of halo and measurement of the intima media complex (IMC). Max IMC, max halo IMC, sum IMC, sum halo IMC, mean IMC, halo count and the Southend halo score were calculated. The provisional OMERACT US score, OGUS, was obtained, taking the average of temporal arteries and axillary arteries IMCs divided by their normal cut-off values. RESULTS Baseline US was positive in 44/47 patients (72% TA, 72% LV). Sensitivity to change of all composite US scores containing TAs was evident by week 8 onward. LVs responded poorly and new axillary US lesions emerged in six patients despite clinical remission. The OGUS showed a large magnitude of change and is considered the score least prone to potential bias. All TA-based US scores showed moderate-strong correlation with disease activity markers. OGUS, TA halo count, Southend TA halo score, TA sum IMC and TA mean IMC showed potential to discriminate remission and relapse with area under the curve ≥0.8. CONCLUSIONS The OGUS is suggested as an outcome measurement for the assessment of treatment response in clinical trials. The abilities of US scores to discriminate remission and relapse are encouraging and should be further explored.

Abstract
Background The present study is the first to explore the correlation between serum folic acid (FA) level and penile arterial peak systolic velocity (PSV) as measured via penile color Doppler ultrasonography (PDU), which directly reflects endothelial function in the penile artery. Materials and methods A total of 244 consecutive erectile dysfunction (ED) patients and 72 healthy controls, recruited from the Andrology department and the Healthy Physical Examination Center of our hospital, respectively, from June 2020 to April 2022, were included in the study. Serum FA was measured in ED patients and healthy controls, and PDU examinations were conducted for all eligible ED patients. The Pearson method was used to evaluate the correlation between FA levels and PDU parameters in ED patients. A receiver operating characteristic (ROC) curve analysis was also performed to calculate the sensitivity and specificity of these parameters for prediction of arteriogenic ED. Results After the PDU test, the average serum FA level among patients diagnosed with arteriogenic ED was 8.08 ± 2.64 ng/ml, lower than the average of 10.78 ± 2.87 ng/ml among healthy controls. There were no statistically significant inter-group differences on any basic parameters, including age, body mass index, fasting blood glucose, total cholesterol, and triglyceride. For further analysis, we divided the arteriogenic ED group into three subgroups by PSV range to compare serum FA levels among these subgroups. The mean FA levels in each of these groups were 5.97 ± 1.51ng/ml, and 8.21 ± 2.37ng/ml, and 10.55 ± 2.56ng/ml, while the corresponding PSV values were 15.75 ± 2.39cm/s, 23.53 ± 2.19cm/s, and 32.72 ± 1.64cm/s. Overall, a positive correlation between PSV and FA level was found among patients with arteriogenic ED (r=0.605, P<0.001). Furthermore, when FA level was used, with a cut-off value of 10.045 ng/ml, as a criterion to distinguish patients with arteriogenic ED from healthy controls, the area under the curve (AUC) was 0.772 (95% confidential interval: [0.696, 0.848]), for a sensitivity of 0.611 and specificity of 0.824. Conclusion Serum FA level is positively correlated with PSV in ED patients, and has the ability to distinguish patients with arteriogenic ED from healthy controls. Taking these findings together, FA deficiency should be regarded as an independent risk factor for arteriogenic ED.

Abstract
BACKGROUND This meta-analysis aimed to investigate the diagnostic value of color ultrasound screening for fetal cardiovascular abnormalities during the second trimester in China. METHODS A literature search was conducted to evaluate the clinical value of color ultrasound screening for fetal cardiovascular abnormalities during the second trimester using English and Chinese databases. Numerical values for sensitivity and specificity were obtained from false-negative, false-positive, true-negative, and true-positive rates, presented alongside graphical representations with boxes marking the values and horizontal lines showing the confidence intervals. Summary receiver operating characteristic (SROC) curves were applied to assess the performance of the diagnostic tests. Data were processed using Review Manager 5.3. RESULTS Four studies (151 patients with fetal cardiovascular abnormalities and 3397 undiagnosed controls) met our evaluation criteria. The sensitivity was 0.91 and 0.96, respectively, and the specificity was 1.00. The Area Under the Curve (AUC) from the SROC curves was >90%; therefore, it was classified as excellent. Furthermore, there were 6 types of fetal cardiovascular abnormalities, and the pooled screening rate of atrioventricular septal defects was the highest. CONCLUSION Our meta-analysis showed that the use of color ultrasound during the second trimester can be an excellent diagnostic tool for fetal cardiovascular abnormalities.

Abstract
BACKGROUND Handheld Doppler is often inaccurate in localization of perforators for pedicled and free flaps. Color Doppler ultrasound (CDU), in contrast, allows more accurate mapping and characterization of perforators to facilitate rapid flap harvest. METHODS Forty-seven flaps harvested from the lower extremity were evaluated preoperatively with CDU by a single surgeon with a conventional low-frequency ultrasound device (Philips Sparq, Cambridge, Mass). Flaps evaluated included profunda artery perforator flaps (n = 36), anterolateral thigh flaps (n = 2), pedicled propeller perforator flaps (n = 7), and toe transfers (n = 2). RESULTS In all cases where a free profunda artery perforator or anterolateral thigh flap was used, the location of the dominant perforator visualized preoperatively correlated exactly with intraoperative findings. In cases where CDU was used preoperatively to locate a large perforator close to a lower extremity defect for reconstruction with a propeller perforator flap, all perforators could be used, and all flaps were successful. CONCLUSIONS Preoperative CDU is particularly useful for flap planning where knowledge of the location of the dominant perforator is critical. This includes planning of thin and superthin free flaps, as well as freestyle perforator flaps. Our clinical experience suggests that this technology should be routinely adopted in certain aspects of reconstructive microsurgery.

Abstract
BACKGROUND Knowledge of normal facial vascular variations could prevent catastrophic complications of cosmetic procedures as well as providing a guide for surgical planning. Color Doppler ultrasound is a safe and noninvasive method for real time vascular evaluation. OBJECTIVE The aim of this study was to evaluate the normal variations of the facial, angular, transverse facial, supratrochlear and supraorbital arteries in a sample of normal individuals. METHODS Normal individuals referred for dermal filler injection to the tertiary dermatologic center, were selected. Patients who were smoker or had a history of facial filler injection, facial surgery, or trauma were excluded from the study. Facial artery at three levels as well as angular, supratrochlear, supraorbital, and transverse facial arteries were evaluated by an 18 MHz ultrasound linear probe regarding their distance from facial reference lines and landmarks, and also their depths in various regions of face. RESULTS A total number of 43 individuals were evaluated in this study. Thirty-one (72.1%) were women. The number of absent facial artery was zero in level one, three (3.48%) in level two, and nine (10.46%) in level three. The angular artery was absent in 10 (11.62%) participants. The transverse facial artery was absent in 27 (31.39%) assessed individuals. Distance from reference lines at level 2 and 3 of facial artery and its depth at level 2 were significantly different between left and right side (p-values: <0.001, 0.01, and 0.03, respectively). No significant difference was seen between depth and distance of two sides for angular and transverse facial arteries. The comparison of the depths and distances from the reference lines of the assessed arteries between two sexes revealed only a significantly greater value of facial artery distance in level 1 in males (p-value: 0.001). BMI was also significantly correlated with the depth of facial artery in level 2 (Pearson correlation coefficient = 0.471, p-value = 0.002) and level 3 (Pearson correlation coefficient = 0.357, p-value = 0.03) and the distance of the facial artery in level 1 (Pearson correlation coefficient = 0.333, p-value = 0.029). CONCLUSIONS Color Doppler ultrasound could be used to map the arteries of face to prevent vascular complications and safely guide cosmetic procedures.

Abstract
PURPOSE Temporal (TA) and axillary (AXA) arteries Color Doppler Ultrasonography (CDUS) is the most reliable diagnostic technique for the diagnosis of giant cell arteritis (GCA), displaying high sensitivity and specificity. Nevertheless, CDUS is still poorly performed in the common clinical practice, being employed only by rheumatologists with a relevant expertise in this field. Color Doppler Eye Ultrasound (CDEUS) is a procedure variously employed in ophthalmology and preliminary findings have displayed a possible role also in the diagnostic work-up of GCA. Aim of this study was to assess whether CDEUS may play a role in the differential diagnosis between arteritic and non-arteritic blindness. METHODS We prospectively included all patients evaluated since September 2021 to May 2022 by our Ophthalmology Unit for sudden blindness and referred to our Vasculitis Clinic in the suspicion of GCA. All patients underwent complete ophthalmological evaluation, routine blood tests, AxA and TA CDUS and CDEUS. According to the definite diagnosis, patients were divided in the following subgroups: (A) patients suffering from arteritic central retinal artery occlusion (CRAO), (B) patients suffering from non-arteritic CRAO, (C) patients suffering from arteritic anterior ischemic optic neuropathy (AION), (D) patients suffering from non-arteritic AION. RESULTS During the observational period, we included a total of 25 patients suffering from sudden blindness and referred to Vasculitis Clinic for ruling out GCA. Patients belonging to group A showed no flow or reduced flow within the territory of central retinal artery (CRA), no "spot sign" and positive TA CDUS; on the other hand, patients from group B presented normal TA CDUS, no flow or reduced flow within the territory of CRA and the presence of "spot sign". Conversely, no relevant difference was evidenced at CDEUS in patients with and without arteritic AION. CONCLUSION Our preliminary data displayed a good reliability of CDEUS in distinguishing between arteritic and non-arteritic CRAO, while no difference was assessed between arteritic and non-arteritic AION. Since AION represents the most common presentation of cranial GCA, CDEUS does not seem a reliable procedure in the diagnostic work-up of GCA and should be restricted only to the exclusion of thrombo-embolic occlusions within the territory of central retinal artery.

Abstract
To probe the diagnostic value of transvaginal color Doppler ultrasonography plus serum β-human chorionic gonadotropin (β-HCG) dynamic monitoring in intrauterine residue after medical abortion.In total, 200 pregnant women undergoing medical abortion in our institution from January 2017 to December 2019 were picked, and assigned to either group A (n = 75, with residue) or group B (n = 125, without residue). We detected serum β-HCG, progesterone (P), follicle stimulating estrogen (FSH) levels and ultrasonic indicators endometrial thickness (ET), peak systolic velocity (PSV), resistance index (RI) values, dissected correlation of indicators using logistic linear regression analysis, and prospected the diagnostic value of relevant indicators in intrauterine residue after medical abortion utilizingreceiver operating characteristic curve.At 7 days after abortion (T3), total vaginal bleeding and visual analogue scalescore in group A were saliently higher in contrast to group B ( P < .05). At 72 hours after abortion (T2) and T3, serum β-HCG, P and FSH levels declined strikingly in both groups, but group B held plainly higher decrease rate than group A ( P HC.05). At T3, ET and PSV levels in both groups considerably waned, whereas RI levels notedly waxed, and group B owned markedly higher decrease/increase than group A ( P wa.05). At T3, serum β-HCG in group A possessed positive association with serum P, FSH, intrauterine ET, PSV levels separately ( P HC.05), whereas negative link with RI levels ( P , .05). The specificity and sensitivity of β-HCG, P, FSH, β-HCG/ET, β-HCG/PSV and β-HCG/RI in the diagnosis of intrauterine residue after medical abortion were high ( P < .05).Serum β-HCG dynamic monitoring plus transvaginal color Doppler ultrasonography is of great value in diagnosing intrauterine residue after medical abortion. Serum β-HCG, P, FSH levels can be combined with the results of intrauterine ET, PSV, RI values, so as to boost the diagnostic accuracy of the intrauterine residue after medical abortion.

Abstract
Color Doppler (CD) imaging is widely used in diagnostics since it allows real-time detection and display of blood flow superimposed on the B-mode image. Nevertheless, to date, a shared worldwide standard on Doppler equipment testing is still lacking. In this context, the study herein proposed would give a contribution focusing on the combination of five test parameters to be included in a novel Quality Assessment (QA) protocol for CD systems testing. A first approach involving the use of the Kiviat diagram was investigated, assuming the diagram area, normalized with respect to one of the gold standards, as an index of the overall Doppler system performance. The QA parameters were obtained from the post-processing of CD data through the implementation of custom-written image analysis methods and procedures, here applied to three brand-new high-technology-level ultrasound systems. Experimental data were collected through phased and convex array probes, in two configuration settings, by means of a Doppler flow phantom set at different flow rate regimes. The outcomes confirmed that the Kiviat diagram might be a promising tool applied to quality controls of Doppler equipment, although further investigations should be performed to assess the sensitivity and specificity of the proposed approach.
