Multidetector CT urography with abdominal compression and three-dimensional reconstruction.

Abstract

849 ainless hematuria is one of the most important warning signs of urologic malignancy, and whereas its causes are numerous, including benign entities, more ominous diagnoses must be excluded by urologic and radiologic evaluation. With the development of helical and, more recently, multidetector CT, unenhanced CT has largely replaced excretory urography in the evaluation of patients presenting with possible renal colic. In most institutions, however, excretory urography remains the mainstay in evaluating patients who present with painless hematuria. Multidetector CT is ideally suited for dynamic multiphase scans and allows the acquisition of Multidetector CT Urography with Abdominal Compression and Three-Dimensional Reconstruction Lawrence C.
