The Role of Apparent Diffusion Coefficient Quantification in Differentiating Benign and Malignant Renal Masses by 3 Tesla Magnetic Resonance Imaging.

Background: Diffusion-weighted magnetic resonance imaging (DWI) is a widely-accepted diagnostic modality whose efficacy has been investigated by numerous past studies in the differentiation of malignant lesions from benign entities.

Aims: The aim of this study was to evaluate the efficiency of diffusion-weighted magnetic resonance imaging in the characterization of renal lesions.

Study Design: Diagnostic accuracy study.

A Rare Anomaly of Biliary System: MRCP Evidence of a Cystic Duct Cyst.

Cystic duct cysts are a rare congenital anomaly. While the other bile duct cysts (choledochus and the intrahepatic bile ducts) are classified according to the classification described by Tadoni, there is no classification method described by the cystic duct cysts, although it is claimed that the cystic duct cysts may constitute a new "Type 6" category. Only a limited number of patients with cystic duct cysts have been reported in the literature.

An incidental case of biliary fascioliasis with subtle clinical findings: US and MRCP findings.

Background: Fascioliasis is a disease caused by the trematode Fasciola hepatica. Cholangitis is a common clinical manifestation. Although fascioliasis may show various radiological and clinical features, cases without biliary dilatation are rare.

Relationship between colon and kidney: a critical point for percutaneous procedures.

Objective: The aim of this study was to determine the frequency of anatomical variations of the colon associated with the kidney.

Material And Methods: A retrospective analysis was performed on 1000 consecutive abdominal computed tomography (CT) scans performed between July 2010 and September 2011. A line parallel to the horizontal plane was drawn through the posterior edge of each kidney at three renal levels: upper, middle and lower pole.
