Kidney cystic formations are a common finding during ultrasound, computed tomography and magnetic resonance imaging. Most kidney cysts are benign, however, in 5–7 % of cases, renal cell carcinoma can be represented by a complex cystic formation. The Bosniak classification allows you to determine the risk of a malignant process and, depending on the assignment of the resulting image to a category, plan treatment tactics. The classification was initially based on the characteristics of cysts according to computed tomography data. Other methods of radiation imaging, such as magnetic resonance imaging and ultrasound, are now also used to characterize complex cystic lesions. The article provides data on the assessment of renal cystic formations according to the Bosniak classification according to modern clinical guidelines, including the use of multiparametric ultrasound

Background: The objective of this study was to evaluate the role of multi-detector computed tomography (MDCT) in the detection and differentiation of adnexal masses using post-operative histopathology findings as the gold standard.Methods: One hundred and forty five cases that were referred with a primary diagnosis of adnexal masses on clinical or USG examination were evaluated by MDCT in the Department of Radiodiagnosis from January 2013 to December 2013. One hundred twelve cases subsequently underwent surgical exploration and histopathological examination, which was used as a control for the evaluation of MDCT findings, were included in this study.Results: Majority (54.5%) of the patients were in the age group of 31-50 years. MDCT detected   adnexal masses as malignant in 56 cases, while in other 56 cases it read adnexal masses as benign. Final histopathology revealed adnexal masses in 57 (51%) cases as malignant while in 55 (49%) cases as benign. There were three cases which on MDCT appeared as malignant were subsequently found to be benign in histopathology. Similarly there were four cases which on MDCT appeared as benign were subsequently proved to malignant in histopathology. The sensitivity, specificity, Positive predictive value and negative predictive value of MDCT for diagnosing a malignant adnexal mass was 93.0%, 94.5%, 94.6% and 92.8% respectively. MDCT findings more predictive of malignancy were solid or cystic-solid mass, necrosis in a solid lesion, cystic lesion with thick, irregular walls or septa, and/or with papillary projections. The presence of ascites, peritoneal metastases, and lymphadenopathy were also helpful to confirm malignancy.Conclusions: MDCT is an excellent and accurate non-invasive modality in the detection and characterization of adnexal masses from benign and malignant

Background-Diagnostic imaging is an important tool to evaluate pancreatic neoplasms. Accurate detection and staging are essential for ensuring appropriate selection of patients who will benefit from surgery and for preventing unnecessary surgeries in patients with unresectable disease. Ultrasound (US), multidetector computed tomography (MDCT) with multiplanar reconstruction and magnetic resonance imaging (MRI) can help to do a correct diagnosis. Methods- Hospital based cross-sectional and quantitative study. Patients with suspected pancreatic mass lesions referred to Department of Radiodiagnosis and Modern Imaging and to Department of Gastroenterology for MDCT and EUS respectively. Results- EUS sensitivity was 98.00%, specificity was 75.00% and by CT scan sensitivity was 93.00%, specificity was 88.00% for mass detection. EUS sensitivity was 88.00%, specificity was 72.00% and of CT scan sensitivity was 76.00%, specificity was 100.00% in detection of vascular involvement. EUS sensitivity was 86.00%, specificity was 74.00% and by CT scan sensitivity was 92.00%, specificity was 100.00% for detection of lymphadenopathy. Conclusion- In conclusion, our results showed that CT with pancreas protocoland EUS correlate moderatelywell in terms of mass detection, masssize, vascular involvement and lymphadenopathy. Keywords: CT, EUS, Pancreatic lesion.

Background: Radiological imaging methods used at a large scale in the assessment of hepatic lesions include: Ultrasound, computed tomography and magnetic resonance. To further characterize these lesions, specific contrast agents may be added, thus revealing the vascularity of the lesions. Discussion: This review focuses on gadoxetic acid, which is a hepatospecific contrast agent used in MRI. The aim of the review is to briefly explain the mechanism of GA enhancement, describe the enhancement patterns of some benign and malignant hepatic lesions and discuss possible advantages of GA over standard contrast agents. Conclusion: The role of GA in functional MR cholangiography and the idea of accessing liver function by measuring parenchymal enhancement will also be explained.

Radiological Aspect

AbstractAcute pancreatitis is one of the most commonly encountered etiologies in the emergency setting, with a broad spectrum of findings that varies in severity from mild interstitial pancreas to severe forms with significant local and systemic complications that are associated with a substantial degree of morbidity and mortality. In this article the radiological aspect of the terminology and classification of acute pancreatitis are reviewed. The roles of ultrasound, computed tomography, and magnetic resonance imaging in the diagnosis and evaluation of acute pancreatitis and its complications are discussed. The authors present a practical image-rich guide, applying the revised Atlanta classification system, with the goal of facilitating radiologists to write a correct report, and reinforcing the radiologist’s role as a key member of a multidisciplinary team in treating patients with acute pancreatitis. Computed tomography is the most performed imaging test for acute pancreatitis. Nevertheless, MRI is useful in many specific situations, due to its superiority soft tissue contrast resolution and better assessment of biliary and pancreatic duct, for example in the ductal disconnection. The purpose if this article is to review recent advances in imaging acquisition and analytic techniques in the evaluation of AP.
