CT angiography and arterial DSA in the evaluation of occlusive processes in pelvic arteries. Initial results

摘要: UNLABELLED 32 patients with iliac artery stenosis and occlusion were studied by means of CT angiography. The results compared the intraarterial digital subtraction angiography (DSA). Postprocessing was performed Maximum Intensity Projection (MIP) 3-D-display. RESULTS 1. MIP: 27/37 stenoses/occlusions correctly assessed, underestimation 5 (4 stenoses, one occlusion), overestimation stenoses. 2. 3-D-Display: 22/37 9/37 (8 two false negative (one stenosis, 4/37 MIP technique proved to be only method display localisation vascular calcifications their exact topographical relationship stenoses occlusions. also valuable in controlling position intravascular stents. Complementary DSA, therefore seems a clinically for calcified noncalcified
