OBJECTIVE Minimal-fat angiomyolipoma resembles renal cell carcinoma (RCC) on imaging. The purpose of this study was to evaluate the diagnostic accuracy of unenhanced CT to diagnose minimal-fat angiomyolipoma. MATERIALS AND METHODS Consecutive patients who underwent unenhanced CT before resection of a solid renal mass from 2002 to 2012 were included in(More)
Segmental enhancement inversion (SEI) is a controversial imaging finding reportedly specific for the diagnosis of renal oncocytoma. The purpose of this study was to re-evaluate SEI using biphasic CT and multiphase MRI.

INTRODUCTION To evaluate extra-prostatic extension (EPE) comparing PI-RADS to non-standardized reporting. MATERIALS AND METHODS With IRB approval, 145 consecutive patients underwent radical prostatectomy (RP) and multi-parametric (T2W+DWI+DCE) MRI between 2012 and 2013. Eighty patients (66.3% with EPE) were staged without PI-RADS and 65 patients (64.6%(More)
AIM To compare echo-planar imaging (EPI) of the liver at 1.5 and 3 T. MATERIALS AND METHODS Under a waiver from the institutional review board, 46 patients underwent respiratory-triggered fat-suppressed b = 50 s/mm(2) EPI at 1.5 or 3 T between 2010-2013. Thirty liver lesions were included with no therapy performed between studies. Signal- and(More)
