Lower extremity spiral CT angiography versus catheter angiography.
Both catheter and spiral computed tomography (CT) angiography of the lower extremity vasculature were performed in six patients with clinically symptomatic peripheral vascular disease. Forty-eight arteries were studied and were independently evaluated for arterial stenoses and occlusions. Compared with catheter arteriography, CT angiography correctly depicted segmental occlusions and significant stenoses (> 50%) in 26 of 28 arteries, yielding a sensitivity of 92.9%, a specificity of 96.2%, and an overall accuracy of 95.5%.
