摘要: PURPOSE: To summarize and compare the published data on gadolinium-enhanced magnetic resonance (MR) angiography color-guided duplex ultrasonography (US) for work-up peripheral arterial disease. MATERIALS AND METHODS: Studies between January 1984 November 1998 were included if (a) MR and/or US performed evaluation of stenoses occlusions in disease lower extremities, (b) conventional was reference standard, (c) absolute numbers true-positive, false-negative, true-negative, false-positive results available or derivable. RESULTS: With a random effects model, pooled sensitivity (97.5% [95% CI: 95.7%, 99.3%]) higher than that (87.6% 84.4%, 90.8%]). Pooled specificities similar: 96.2% (95% 94.4%, 97.9%) 94.7% 93.2%, 96.2%) US. Summary receiver ...
