AIM A series of rare complicated duodenal diverticula were reported with emphasis on causes for misdiagnosis. MATERIAL AND METHODS Patients with a discharge diagnosis of complicated duodenal diverticulum were retrospectively obtained. Computed tomographic (CT) reports and findings were reviewed. RESULTS Complications consisted of diverticulitis (n=2),(More)
OBJECTIVES To evaluate an algorithm integrating ultrasound and low-dose unenhanced CT with oral contrast medium (LDCT) in the assessment of acute appendicitis, to reduce the need of conventional CT. METHODS Ultrasound was performed upon admission in 183 consecutive adult patients (111 women, 72 men, mean age 32) with suspicion of acute appendicitis and a(More)
PURPOSE To report the first results of hybrid (18)F-fluorocholine PET/MRI imaging for the detection of prostate cancer. METHODS This analysis included 26 consecutive patients scheduled for prostate PET/MRI before radical prostatectomy. The examinations were performed on a hybrid whole-body PET/MRI scanner. The MR acquisitions which included T2-weighted,(More)
PURPOSE To assess the influence of perfusion on apparent coefficient diffusion (ADC) maps, the contribution of b-value images, and the number of b-values needed in prostate cancer detection by diffusion-weighted imaging (DWI). MATERIALS AND METHODS Patients scheduled for prostatectomy were scanned by 3T magnetic resonance imaging (MRI) with DWI based on(More)
We report a rare case of an isolated and unsuspected thrombosis in the right internal iliac vein. The presentation was atypical with regard to the clinical manifestations and the thrombus location. The patient was admitted for an acute abdominal pain in the right iliac fossa. The thrombosis was suspected on the basis of a portal-phase contrast-enhanced(More)
PURPOSE To compare readout-segmented echo-planar imaging (EPI) (RESOLVE) to single-shot EPI (ss-EPI) diffusion-weighted imaging (DWI) for the assessment of renal interstitial fibrosis. MATERIALS AND METHODS A phantom, eight healthy volunteers (under 30 years to avoid age-fibrosis related) and 27 chronic kidney disease (CKD) patients (scheduled for kidney(More)
A need exists to noninvasively assess renal interstitial fibrosis, a common process to all kidney diseases and predictive of renal prognosis. In this translational study, Magnetic Resonance Imaging (MRI) T1 mapping and a new segmented Diffusion-Weighted Imaging (DWI) technique, for Apparent Diffusion Coefficient (ADC), were first compared to renal fibrosis(More)
Urothelial carcinomas are the fourth most common tumors in men. Upper tract urinary carcinomas (UTUCs) are uncommon and represent only 5-10% of urothelial carcinomas.(1) Metastatic testicular cancers are rare and primary tumor sources are the prostate, lung, and gastrointestinal tract. We report the first case of testicular metastasis 2 years after initial(More)
