Abstract The aim of this study is to compare the diagnostic performance of Color flow Doppler ultrasound and Contrast enhanced MR angiography for the evaluation of peripheral arterial occlusive disease taking Intra-arterial digital subtraction angiography as a gold standard. The study was conducted on 16 patients (10 male and 6 female). Their ages ranged from 38 to 70 years (mean 53 years). Patients were presented by critical ischemia or Disabling claudication. Color Doppler US, contrast enhanced MR angiography and Intra-arterial digital subtraction angiography for all In CFDUS the aorto-iliac and femoro-popliteal segments were evaluated for detection of the degree of stenosis and out of the 127 interpretated segments, 54 abnormal segments were detected; one aneurysm, 19 nonsignificant stenoses, 19 significant stenoses and 15 occlusions. The infrapopliteal segments were evaluated as patent or occluded segments and out of 60 interpretated segments, 28 occlusions were detected. Out of 306 interpretated segments with CE-MRA, 115 abnormal segments were detected; one aneurysm, 34 nonsignificant stenoses, 27 significant stenoses and 54 occlusions. The diagnostic performance of CE-MRA is proved to be higher than CFDUS. In this study, we recommended that patients with PAOD are examined with CFDUS that can accurately detect normal patients, patients with nonsignificant lesions, patients amenable to endoluminal intervention. It can also detect patients with multisegmental occlusive disease who will pass to CE-MRA before bypass graft for detection of the sites of graft anastmosis. |
