Abstract
OBJECTIVE To explore the discriminatory diagnostic value of multimodal ultrasound(US) combined with blood cell analysis (BCA) for Granulomatous Lobular Mastitis (GLM) and Invasive Ductal Carcinoma (IDC) of the breast. METHODS A total of 157 breast disease patients were collected and divided into two groups based on postoperative pathological results: the GLM group (57 cases with 57 lesions) and the IDC group (100 cases with 100 lesions). Differences in multimodal ultrasound features and the presence of BCA were compared between the two groups. The receiver operating characteristic (ROC) curve was used to calculate the optimal cutoff values, sensitivity, specificity, 95% confidence interval (CI), and the area under the curve (AUC) for patient age, lesion size, lesion resistive index (RI), and white blood cell (WBC) count in BCA. Sensitivity, specificity, positive predictive value, negative predictive value, diagnostic accuracy, and AUC were calculated for different diagnostic methods. RESULTS There were statistically significant differences (P < 0.05) observed between GLM and IDC patients in terms of age, breast pain, the factors in Conventional US (lesion size, RI, nipple delineation, solitary/multiple lesions, margin, liquefaction area, growth direction, microcalcifications, posterior echogenicity and abnormal axillary lymph nodes), the factors in CEUS (contrast agent enhancement intensity, enhancement pattern, enhancement range, and crab-like enhancement) and the factors in BCA (white blood cells, neutrophils, lymphocytes and monocytes). ROC curve analysis results showed that the optimal cutoff values for distinguishing GLM from IDC were 40.5 years for age, 7.15 cm for lesion size, 0.655 for lesion RI, and 10.525*109/L for white blood cells. The diagnostic accuracy of conventional US combined with CEUS (US-CEUS) was the highest (97.45%). The diagnostic performance AUCs for US-CEUS, CEUS, and US were 0.965, 0.921 and 0.832, respectively. CONCLUSION Multifactorial analysis of multimodal ultrasound features and BCA had high clinical application value in the differential diagnosis of GLM and IDC.

Abstract
In the head and neck area, a large proportion of clinically relevant fistulas occur in childhood. The present case describes the use of contrast enhanced ultrasound with intraductal administration of the contrast medium for preoperative visualization of the fistula duct in the case of a second brachial cleft fistula. This provided the surgeon with important additional information, such as the detailed course of the fistula and its relation to the large vessels of the neck. The method can help to improve surgical planning, reduce radiation exposure and to avoid imaging under general anesthesia, especially in children.

Abstract
AIM To examine to what extent the high frame rate contrast-enhanced ultrasound (HiFR) diagnostic enables the conclusive diagnosis of liver changes with suspected malignancy. MATERIAL/METHODS Ultrasound examinations were performed by an experienced examiner using a multifrequency probe (SC6-1) on a high-end ultrasound system (Resona 7, Mindray) to clarify liver changes that were unclear on the B-scan. A bolus of 1-2.4 ml of the Sulphur hexafluoride ultrasound microbubbles contrast agent SonoVue™ (Bracco SpA, Italy) was administered with DICOM storage of CEUS examinations from the early arterial phase (5-15 s) to the late phase (5-6 min). Based on the image files stored in the PACS, an independent reading was performed regarding image quality and finding-related diagnostic significance (0 not informative/non-diagnostic to 5 excellent image quality/confident diagnosis possible). References were clinical follow-up, if possible, comparison to promptly performed computed tomography or magnetic resonance imaging, in some cases also to histopathology. RESULTS We examined 100 patients (42 women, 58 men, from 18 years to 90 years, mean 63±13 years) with different entities of focal and diffuse liver parenchymal changes, which could be detected in all cases with sufficient image quality with CEUS and with high image quality with HiFR-CEUS. Proportionally septate cysts were found in n = 19 cases, scars after hemihepatectomy with local reduced fat in n = 5 cases, scars after microwave ablation in n = 19 cases, hemangiomas in n = 9 cases, focal nodular hyperplasia in n = 8 cases, colorectal metastases in n = 15 cases, hepatocellular carcinoma (HCC) in n = 11 cases, Osler disease in n = 8 cases. The size of lesions ranged from 5 mm to 200 mm with a mean value of 33.1±27.8 mm. Conclusive diagnoses could be made by the experienced investigator in 97/100 cases with CEUS, confirmed by reference imaging, in parts by histopathology or follow-up. The image quality for HiFR CEUS was rated with a score of 3 to 5; 62 cases were assessed with an average of good (4 points), 27 cases with very good (5 points), and in 11 cases (3 points) still satisfactory despite aggravated acoustic conditions. The specificity of HIFR-CEUS was 97%, the sensitivity 97%, the positive predictive value 94%, the negative predictive value 99% and the accuracy 97%. CONCLUSION HIFR-CEUS has demonstrated has demonstrated an improved image quality resulting in a high diagnostic accuracy. In the hands of an experienced investigator, HiFR-CEUS allows the assessment of focal and diffuse unclear liver parenchymal changes on B-scan and dynamic assessment of microcirculation in solid and vascular changes.

Abstract
BACKGROUND Ultrasound is one of the most important imaging methods in the daily routine. Contrast-enhanced ultrasound (CEUS) has put ultrasound on equal footing with computed tomography and magnetic resonance imaging in many areas. Although ultrasound contrast agents are commonly administered intravenously, endocavitary application as performed in the case of iodine-containing contrast agents is also possible. METHOD Based on the current literature, this overview provides information regarding possible endocavitary applications of ultrasound contrast agents as they are used and could be used in the daily routine in radiology. Examples are provided to illustrate the advantages and disadvantages of clinical use. RESULTS AND CONCLUSION Endocavitary CEUS broadens the spectrum of possible ultrasound applications and can be safely used for patient diagnosis and treatment. The method can be safely used for diagnosis and patient management, particularly in patients in whom examinations including exposure to radiation with iodine-containing contrast agents may be contraindicated and who have limited mobility due to disease severity. KEY POINTS · Endocavitary CEUS is a safe method that can be readily learned by those with prior ultrasound training. Radiologists benefit from their existing knowledge of contrast-enhanced imaging.. · With ultrasound contrast agents, endocavitary examinations comparable to CT and fluoroscopy can be performed without having to take radiation exposure, preexisting conditions, and patient mobility into consideration.. · In principle, endocavitary CEUS can access every body cavity (physiological and pathological) and body orifice with any access device.. · The method is mainly used for interventions including puncture and drainage. The diluted ultrasound contrast agent can be continuously visualized in the access device and in the target region, including distribution within the target region, with high spatial and temporal resolution. Voiding urosonography and visualization of the salivary duct system should also be mentioned in the radiological context.. · Poor B-mode imaging conditions typically also mean poor CEUS conditions. Imaging methods that can reliably evaluate low-lying structures and structures with overlying air, particularly in obese patients, without artifacts and can provide a good overview have a clear advantage here..
