Infrarenal Abdominal Aortic Aneurysms at Multi–Detector Row CT Angiography: Intravascular Enhancement without a Timing Acquisition

In 70 patients referred for evaluation of aortoiliac aneurysm disease, multi–detector row computed tomography was performed with a uniform 25-second delay from the initiation of intravenous administration of a 150-mL bolus of contrast material at 4 mL/sec. In all patients, adequate enhancement (>200 HU) of the aorta and intense enhancement of iliofemoral runoff was achieved without venous contamination.
