Computed Tomography Urography With 16-Channel Multidetector Computed Tomography: A Pictorial Review

Excretory phase computed tomography (CT) urography obtained with a 16-slice multidetector CT scanner using thin-section images (slice thickness = 0.75 mm, reconstruction increment = 0.5 mm) combined with interactive reformatted and 3-dimensional reconstruction techniques, high spatial resolution images of the urinary tract similar to those of classic intravenous urography can be produced. The purpose of this pictorial essay is to review the early experience of the authors and to show the wide range of abnormalities of the urinary tract detected with this technique.
