Abstract
AIM To compare efficiency levels between radiologist and radiology resident and any significant or clinically relevant differences in breast ultrasound diagnosis, thus reducing extra costs. MATERIAL AND METHODS 100 patients attending for breast ultrasound were included. Each patient was examined by a radiologist, and subsequently by a resident of the radiology department. Both operators noted their findings and wrote a concluding report. Reports were compared for histological and biological analysis. RESULTS 100 female patients with a mean age about 49 years were examined. The proportions of correct diagnoses of lesions individuated by radiologist and resident were 26.90 > 13.71% (p-value = 10.7), i.e. the radiologist was more accurate in comparison to resident in the individuation of breast lesions. CONCLUSIONS The radiologist was more accurate in comparison to radiology resident in the evaluation of breast pathology in ultrasonography diagnoses, and this could reduce cost and/or in-depth analysis.

Abstract
Presbyphagia represents the physiological aging evolution of the swallowing function. It is related to the natural changes of the anatomical structures involved in the swallowing process. These age-related modifications can be asymptomatic in the early stages of life, but in the late stages, they could lead to dysphagia, aspiration pneumonia, dehydration, or malnutrition, reducing the quality of life. Videofluoromanometry (VFM) is the combined study of videofluoroscopy (VFS) and oropharyngeal manometry that allows simultaneous identification of functional and morphological features of the presbyphagia, also in asymptomatic otherwise healthy elderly adults. This study retrospectively evaluated the effectiveness of the VFM and the role of a multidisciplinary team of specialists in the analysis of a large cohort of old patients with presbyphagia, with the objective of achieving early diagnosis of the disease and the best therapy to delay the development of complications such as aspiration pneumonia, malnutrition, and dehydration.

Abstract
Orofacial granulomatosis is a unifying term comprising a variety of clinical conditions involving the face and the oral cavity and histologically characterized by the presence of chronic granulomatous inflammation. Lip swelling and erythema are the most frequent clinical signs. We report on the clinical-pathological features and the management of two cases of orofacial granulomatosis characterized by gingival onset, without other local and systemic manifestations. The diagnosis of orofacial granulomatosis with gingival onset is made by the exclusion of other conditions exhibiting gingival inflammation and/or enlargement. Detailed medical history, haematological investigations and gingival biopsy are fundamental for the definitive diagnosis. Though infrequent, orofacial granulomatosis with gingival involvement should be considered in the differential diagnosis of hyperplastic gingivitis of uncertain origin.

Abstract
Intestinal pneumatosis (IP) has been traditionally associated with intestinal infarction and poor outcome in adults; recent studies have questioned its clinical value. To assess its diagnostic and prognostic significance, we have retrospectively evaluated 102 patients correlating the CT finding of gastrointestinal parietal gas with clinical data and outcome. Fifty-three patients (52%) had surgical evidence of intestinal infarction. In the remaining patients, a variety of lesions were found including intestinal obstruction, cancer, volvulus, ulcer, hernia, trauma, Crohn's disease, diverticulitis, and iatrogenic causes. We observed the presence of portal vein gas (PVG) associated to IP in 25.5% of cases. In patients having both IP and PVG, intestinal infarction was observed in 69.2% of cases. In our series, overall mortality was 30.4% (31/102), and when PVG was present, it rose to 50% (13/26). In our study, IP has been observed in a broad range of lesions with very different prognosis, the most frequent of which was intestinal infarction. When associated to PVG, there was a much higher prevalence of intestinal infarct, and the prognosis was definitively worse.

Abstract
Ischemic colitis (IC) is the most common vascular disorder of the gastrointestinal tract with a reported incidence of 6.1-44 cases/100,000 person years with confirmatory histopathology. However, the true incidence of IC poses some difficulty, and even vigilant clinicians with patients at high risk often miss the diagnosis, since clinical presentation is non-specific or could have a mild transient nature. Detection of IC results is crucial to plan the correct therapeutic approach and reduce the reported mortality rate (4-12%). Diagnosis of IC is based on a combination of clinical suspicion, radiological, endoscopic and histological findings. Some consider colonoscopy as a diagnostic test of choice; however, preparation is required and it is not without risk, above all in patients who are severely ill. There are two manifestations of vascular colonic insult: ischaemic and reperfusive. The first one occurs above all during ischaemic/non-occlusive mesenteric ischaemia; in this case, the colonic wall appears thinned with dilated lumen and fluid appears in the paracolic space. When reperfusion occurs, the large bowel wall appears thickened and stratified, because of subepithelial oedema and/or haemorrhage, with consequent lumen calibre reduction. Shaggy contour of the involved intestine and misty mesentery are associated with the pericolic fluid. The pericolic fluid results are a crucial finding for IC diagnosis since its evidence suggests the presence of an ongoing damage thus focusing the attention on other pathological aspects which could be otherwise misdiagnosed, such as thinned or thickened colonic wall. Moreover, the pericolic fluid may increase or decrease, depending on the evolution of the ischaemic damage, suggesting the decision of medical or surgical treatment. Radiologists should not forget the hypothesis of IC, being aware that multidetector CT could be sufficient to suggest the diagnosis of IC, allowing for early identification and grading definition, and in a short-term follow-up, discriminating patients who need urgent surgery from patients in whom medical treatment and follow-up can be proposed.

Abstract
OBJECTIVES We compared the efficacy of non-anatomical lung resections with that of three other techniques: monopolar electrocautery; neodymium-doped yttrium aluminium garnet laser and harmonic technology. We hypothesized that the thermal damage with harmonic technology could be reduced because of the lower temperatures generated by harmonic technology compared with that of other devices. METHODS Initial studies were performed in 13 isolated pig lungs for each group. A 1.5-cm capsule was inserted within the lung to mimic a tumour and a total of 25 non-anatomical resections were performed with each device. The damage of the resected lung surface and of the tumour border were evaluated according to the colour (ranging from 0-pink colour to 4-black colour), histological (ranging from Score 0-no changes to Score 3-presence of necrotic tissue) and radiological (ranging from Score 0-isointense T2 signal at magnetic resonance imaging to Score 3-hyperintense T2 signal) criteria. A total of seven non-anatomical resections with harmonic technology were also performed in two live pigs to assess if ex vivo results could be reproducible in live pigs with particular attention to haemostatic and air-tightness properties. RESULTS In the ex vivo lung, there was a statistical significant difference between depth of thermal damage (P < 0.0001) in electrocautery (1.3 [1.2-1.4]), laser (0.9 [0.6-0.9]) and harmonic (0.4 [0.3-0.5]) groups. Electrocautery had a higher depth of thermal damage compared with that of the laser (P = 0.01) and harmonic groups (P = 0.0005). The harmonic group had a less depth of thermal damage than that of the laser group (P = 0.01). Also, histological damages of tumour borders (P < 0.001) and resected lung surface (P < 0.001), radiological damage of tumour borders (P < 0.001) and resected lung surface (P < 0.001) and colour changes (P < 0.001) were statistically different between three study groups. Resections of in vivo pig lungs showed no bleeding; 2 of 7 cases of low air leaks were found; however, they ceased by sealing lung parenchyma with harmonic technology. CONCLUSIONS Our experimental data support the resections performed with the use of harmonic technology. The lack of severe tissue alterations could favour healing of parenchyma, assure air tightness and preserve functional lung parenchyma. However, randomized controlled studies are needed in an in vivo model to corroborate our findings.

Abstract
We investigate the electro-optic properties of black phosphorus (BP) thin films for optical modulation in the mid-infrared frequencies. Our calculation indicates that an applied out-of-plane electric field may lead to red-, blue-, or bidirectional shift in BP's absorption edge. This is due to the interplay between the field-induced quantum-confined Franz-Keldysh effect and the Pauli-blocked Burstein-Moss shift. The relative contribution of the two electro-absorption mechanisms depends on doping range, operating wavelength, and BP film thickness. For proof-of concept, simple modulator configuration with BP overlaid over a silicon nanowire is studied. Simulation results show that operating BP in the quantum-confined Franz-Keldysh regime can improve the maximal attainable absorption as well as power efficiency compared to its graphene counterpart.

Abstract
OBJECTIVE To investigate the CT features of reperfusion (presence/absence) in non-occlusive mesenteric ischaemia (NOMI) and their prognostic value in an emergency setting. METHODS A revision was undertaken of imaging from 20 patients (16 males/4 females) with a dismissal summary of NOMI. All patients had previously undergone a minimum of one multidetector CT examination, and consequently underwent surgery (n = 8), autopsy (n = 2), angiography (n = 1) or endoscopy (n = 9). An evaluation of the CT scans was conducted to determine vessels, mesentery, bowel and peritoneal cavity features. The superior mesenteric artery (SMA) average diameter of NOMI cases were compared with 30 controlled cases. Kappa, Kolmogorov-Smirnov (K-S) and Fisher's exact tests were used for statistical analysis. RESULTS A mean SMA diameter significantly smaller than that of the controlled cases was found for patients with NOMI (K-S test: D = 0.75, p = 3.7 × 10-08). Fisher's exact tests showed a strong connection between the presence of reperfusion and mesenteric fat stranding (p = 0.026), bowel wall thickening (p = 3.2 × 10-05) and a high attenuation of the bowel wall on unenhanced CT images (p = 2.8 × 10-04). A reduction in mortality was significantly linked to the combination of normal mesenteric vessels and wall thickening (p = 0.034). CONCLUSION Analysis of not only vessels findings but also mesentery and bowel CT features will support the identification of NOMI with or without a reperfusion event in an emergency setting. A strong correlation between some CT features and lower mortality exists. ADVANCES IN KNOWLEDGE CT features of NOMI with or without reperfusion are demonstrated. Correctly assessing the presence of reperfusion in NOMI, may allow better management of these conditions in the emergency setting.

Abstract
AIM The aim of this paper was to assess the origin and course variations of vessels forming the renal vascular pedicle. METHODS The IRB approved study retrospectively evaluated 921 consecutive patients (503 females, 418 males; mean age, 54 years), who underwent multidetector computed tomographic (MDCT) of the abdomen for various purposes at our Department of Radiology, between January 2012 and December 2013. Multiplanar and volumetric reformations were performed in all cases. For each set of images, the locations of renal artery origins and renal venous drainage, such as all renal vessels variations, including division variations and presence of extrarenal vessels, were investigated. RESULTS The tract of the aorta between the upper margin of L1 and the lower margin of L2 originated 96% of main renal arteries and 72% of extra renal arteries. The most common location for renal artery origin was the L1- L2 intervertebral disc level. Sixty-nine percent of patients showed a single renal artery, with multiple arteries in 31%, bilateral multiple arteries in 11%, and early division in 6% of cases. Additional renal arteries were detected on the right side in 5% and on the left side in 12% of cases. With regard to the venous drainage, 89.8% of patients showed a single renal vein, with multiple vein in 10.2%, while 23.8% showed a retro-aortic course of the renal vein. CONCLUSION Renal arteries and veins variations of origin and course are not infrequent. Extrarenal vessels may compromise renal surgery. The awareness of any possible renovascular anomaly is crucial in case of a non-invasive diagnostic search for renal artery stenosis, and when renal surgery related to renal arteries is performed, such as in case of interventional radiological procedures, urological and vascular operations, and renal transplantation.

Abstract
Alimentary tract perforation is a frequent emergency condition. Imaging plays an important role to make an accurate diagnosis, defining the presence, the level, and the cause of the perforation, essential information to enable the most correct therapeutic choice. Plain radiography is generally performed as the first choice. In case of a clinically suspected bowel perforation, not detected on x-ray imaging, the contribution of computed tomography is essential. Magnetic resonance is not yet widely used in diagnostic workup of patients with acute abdominal pain, but it can be useful in the differential diagnosis of acute abdomen in specific patients (pregnancy and pediatric patients).

Abstract
PURPOSE This study aimed at comparing the diagnostic accuracy of ultrasonography (US) and magnetic resonance imaging (MRI) for the detection of joint effusion of the knee. METHODS For this retrospective study, approbation by the institutional review board was not required, and written informed consent from the patients was waived. One hundred and fifty-eight patients (83 men and 75 women; median age 41.2 years; age range 13-81 years) who underwent US and MRI of the knee were included in the study. The sensitivity and specificity of US with respect to MRI in the evaluation of the effusion of the knee and in each recess were compared. RESULTS In evaluating joint effusion of the knee, compared with MRI, US correctly identified 78 of 96 patients with joint effusion, showing a sensitivity of 81.3 % and a specificity of 100 %, with a positive predictive value (PPV) of 100 % and a negative predictive value (NPV) of 77.5 % (p value = 0.001). Various results were obtained comparing ultrasound with MRI, regarding the various recesses. CONCLUSION US showed high specificity and sensitivity in diagnosing knee joint effusion and could be used in patients who cannot undergo MRI.

Abstract
Purpose To evaluate safety and efficacy of Trans-Arterial Ethanol-Lipiodol Embolization (TAELE) compared with conventional Trans-Arterial Chemo-Embolization (cTACE) in the treatment of small intermediate-HCC (BCLC-Stage B). Materials and Methods A random sample of 87 patients (37.93% male; 62.07% female; age range, 36–86 years) with documented small intermediate-HCC and treated with TAELE (mixture 1:1 of Ethanol and Lipiodol) or cTACE (mixture of 50mg-Epirubicin and 5cc-Lipiodol) were retrospectively studied in an institutional review board approved protocol. The two procedures were compared with χ2-test, χ2-test with Yates correction, McNemar’s exact test, ANOVA test and log-rank test. Results TAELE and cTACE therapies were performed in 45 and 42 patients, respectively. Thirty days after the procedure, a Multi-Detector Computed Tomography (MDCT) showed no significant difference in the number of patients with partial and complete response between the two groups (p-value = 0.958), according to mRECIST. Contrary, significant differences were found in tumor-devascularization, lesion-reduction and post-embolization syndrome occurrence (p-value = 0.0004, p-value = 0.0003 and p-value = 0.009, respectively). Similar survival was observed during 36-month follow-up (p-value = 0.884). Conclusion Compared to cTACE, TAELE showed a better toxicity profile with similar 36-month survival and similar one-month anti-tumor effects, which makes it better tolerated by patients, especially in case of more than one treatment.

Abstract
PURPOSE The aim of this study was to evaluate the accuracy of tridimensional endoanal ultrasound (3D-EAUS) in the diagnosis of perianal sepsis comparing the results with the surgical findings, considered as reference standard. METHODS From January 2009 to January 2013, all the patients referred for the assessment and treatment of perianal sepsis with suspected anorectal origin were enrolled in the study. All patients gave informed written consent. Prior to surgery, all the patients underwent anamnestic evaluation, clinical examination, and unenhanced and H2O2-enhanced 3D-EAUS. Surgery was performed by a colorectal surgeon blinded to the 3D-EAUS results. RESULTS A total of 212 patients with suspected perianal suppurations were assessed during the study period. In 12 patients, the H2O2-enhanced 3D-EAUS was not performed, and so, they were excluded from the study. Very good agreement between 3D-EAUS and examination under anesthesia (EUA) in the classification of primary fistula tracts (kappa = 0.93) and in the identification of fistula internal opening (kappa = 0.97) was found. There was a good concordance (kappa = 0.71) between 3D-EAUS and surgery in the detection of fistula secondary extensions. The overall sensitivity and specificity of 3D-EAUS in the diagnosis of perianal sepsis were 98.3 and 91.3% respectively. CONCLUSION 3D-EAUS is a safe and reliable technique in the assessment of perianal sepsis. It may assist the surgeon in delineating the fistula tract anatomy and in determining the origin of sepsis, supporting the preoperative planning of definitive and appropriate surgical therapy.

Introduction Peutz–Jeghers syndrome is an autosomal dominant disease with incomplete penetrance and variable expression caused by germline mutation of serine threonine kinase 11/liver kinase B1; it is characterized by hamartomatous polyps in the gastrointestinal tract, mucocutaneous melanin pigmentation, and increased predisposition to neoplasms. In Peutz–Jeghers syndrome, bilateral Sertoli cell testicular tumors cause endocrine manifestations including gynecomastia and feminization. This study aimed to assess the role of breast ultrasound in the evaluation of the effectiveness of an innovative surgical approach. Case presentation This report presents a pair of European 9-year-old identical male twins with Peutz–Jeghers syndrome, bilateral prepubertal gynecomastia, and testicular multifocal calcifications. Both twins were treated with anastrozole for 2 years. After finishing treatment, both underwent subcutaneous mastectomy performed by the “modified” Webster technique. Breast examination and ultrasound were performed before and after the pharmacological and surgical treatment. A breast ultrasound scan before surgery showed bilateral gynecomastia in both patients. No solid nodular or cystic formations were present on either side. After pharmacological therapy and surgical glandular removal, a breast examination showed a significant reduction in breast volume; 1 year after surgery, a breast ultrasound scan of both patients showed a total absence of glandular parenchyma, with muscle planes well represented. Conclusions Breast examination and ultrasound have proved to be a valid approach in the assessment of the treatment of prepubertal gynecomastia because they allow the efficacy of the pharmacological and surgical treatment to be evaluated in a multidisciplinary approach to one of the most frequent endocrine manifestations of Peutz–Jeghers syndrome.

Abstract
INTRODUCTION The popularity of one-piece implants has increased considerably among patients and dentists. The advantages of one-piece immediate loading are to reduce the number of interventions. These parameters can be better controlled with a one-piece implant. METHODS We considered 21 patients with one-piece implants inserted in mandible for this retrospective study. Inclusion criteria were: good oral hygiene, absence of lesions of the oral mucosa, no smoking or smoking less than 20 cigarettes a day, drinking less than two glasses of wine a day, good general health and no pregnancy. RESULTS We enrolled 21 (12 women and 9 men) patients in this retrospective study. The mean follow-up was 1 year. A total of 84 one-piece implants were inserted in mandible to replace 42 lower first and 42 second incisors. The diameter of the implants was 3.0mm in all fixtures. The length of the implants was equal to or longer than 12 mm in 44 and 40 fixtures respectively. Of these, 48 were inserted in women and 36 in men (age range 33 to 67; mean age 58.3 years). CONCLUSIONS There is no difference between the survival rates of one-piece immediate loading implants and two-piece implants and delayed loading. In conclusion, a one-piece immediate loading implant is a reliable device for mandible rehabilitation.

Abstract
PURPOSE To evaluate safety and clinical efficacy of percutaneous transcatheter embolization (PTE) in the treatment of spontaneous bleedings (SBs) in patients submitted to chronic anticoagulation therapy. MATERIALS AND METHODS From January 2007 to December 2012, 20 patients (mean age 75.8 years, range 68-91 years) with 23 SBs were retrospectively evaluated. Active bleeding was documented by contrast enhanced-multidetector row computed tomography (CE-MDCT). PTE was performed using different embolic agents. Technical success (TS), clinical success (CS), late success (LS) and mortality rate (M) related to the angiographic procedure and complications were evaluated. RESULTS CE-MDCT and digital subtraction angiography (DSA) identified active bleeding sites in 18 cases (18/20). In two cases (2/20) DSA did not confirm the arterial bleeding diagnosed on CE-MDCT. Twenty-three sessions of PTE were performed. TS, CS, LS and M were, respectively, 100, 85, 15 and 0%. No major complications were observed. CONCLUSIONS PTE could be considered a safe and effective "first line" approach to treat SB associated with anticoagulation therapy.

Abstract
Ingestion, inhalation, and insertion of foreign bodies (FBs) are very common clinical occurrences. In any case, early diagnosis and prompt management are mandatory to avoid severe and life-threatening complications. Radiologists have an important role in revealing the presence, dimension, nature, and relationship with anatomical structures of a FB; selecting the most appropriate imaging modality; and enabling the best therapeutic choice. This review article focuses on the most frequent FBs ingested, inhaled, and inserted and presents the different tests and investigations to provide a correct radiological approach.

Abstract
PURPOSE This study was done to evaluate the possibility of reducing the dose of ionising radiation by using dual-source dual-energy computed tomography (CT) in patients undergoing CT angiography of the aorta to search for endoleaks after endovascular aneurysm repair (EVAR). MATERIALS AND METHODS One hundred and forty-eight patients (117 M, 31 F; mean age 75 ± 6.5) underwent 171 CT angiography scans for follow-up after EVAR. For each patient we performed a triple-phase acquisition protocol consisting of a nonenhanced phase, an arterial phase and a delayed phase; the latter acquired in dual energy. Two radiologists jointly evaluated the nonenhanced, arterial and delayed phase, and a third radiologist evaluated only the delayed phase and its virtual noncontrast (VNC) reconstruction. Moreover, we compared the cumulative effective doses of the triple-phase acquisition with the dual-energy acquisition. RESULTS We detected 34 endoleaks (19.8 %), with 100 % agreement between the triple-phase and dual-energy acquisitions. The effective dose of dual-energy acquisition performed during the delayed phase was 61.7 % lower than that of the triple-phase acquisition. CONCLUSIONS A dual-energy CT scan acquired during the delayed phase and its VNC reconstruction allow detection of endoleaks with a substantial reduction of effective dose and a complete diagnostic agreement with a triple-phase acquisition protocol.
