CT urography of a vesicourachal diverticulum containing calculi.

Urachal remnant disease is a relatively rare urological condition that presents a variety of clinical problems in adult patients. Contrast-enhanced multi-detector row computed tomography (MDCT) urography is a new diagnostic imaging technique providing comprehensive evaluation of the upper and lower urinary tract. MDCT urography performed with a combination of unenhanced, nephrographic phase, and excretory- phase imaging can demonstrate a wide spectrum of disease in these patients with a single study.

Can multidetector row CT visualize the right and left inferior phrenic artery in a population without disease of the liver?

Purpose: To determine the ability to visualize the origin of the right inferior phrenic artery (RIPA) and the left inferior phrenic artery (LIPA) by multidetector row computed tomography (MDCT) in a population without disease of the liver.

Methods: The origin of the RIPAs and the LIPAs were evaluated using arterial-phase MDCT images in 200 patients.

Results: The RIPA origin was detected in all cases, while LIPA origin was detected in 193 (96.
