Evaluation of primary prostate cancer using 11C-methionine-PET/CT and 18F-FDG-PET/CT.

Objective: The objective of this study was to evaluate the capability of (11)C-methionine (MET)-PET/CT and (18)F-2-deoxy-2-fluoro-D: -glucose (FDG)-PET/CT to diagnose primary prostate cancer using recently developed Gemini TF PET/CT (Philips Healthcare, Cleveland, OH).

Methods: Twenty men who had been referred for a diagnostic work-up for prostate cancer were enrolled in this study. MET- and FDG-PET/CT by high-resolution mode were carried out on the same day prior to prostate biopsy and each maximum standardized uptake value (SUVmax) was compared with the pathological findings.

Minimally invasive diagnosis of persistent sciatic artery by multidetector-row computed tomographic angiography.

Persistent sciatic artery is a rare but potentially significant vascular anomaly that is associated with a high incidence of aneurysm formation and limb-threatening ischemic complications. The diagnosis of persistent sciatic artery has usually been made by conventional angiography. We report a case of occluded and patent persistent sciatic arteries in which multidetector-row computed tomographic angiography allowed a definitive diagnosis of this rare vascular condition.
