Computed Tomography for Noninvasive Imaging of the Iliac Arteries

Abstract

Angiography has been the standard means of preoperative evaluation of the arterial system. Although the noninvasive modalities (sonography, nuclide "flow" studies, and computed tomography) are also frequently used in preoperative arterial evaluation, they are generally followed by arteriography. We propose that in some instances computed tomography may be the sole means of preoperative evaluation and that sufficient information may be obtained with a high-dose contrast technic to plan the surgical intervention.
