TL;DR
The purpose was to estimate the sensitivity and specificity of noninvasive carotid artery tests using formal meta-analysis and to determine which tests are the most discriminating in the detection of carotID artery occlusion and severe disease.
Abstract
Carotid duplex ultrasonography, carotid Doppler ultrasonography, and magnetic resonance angiography are all similarly successful at predicting 100% carotid artery occlusion and 70% stenosis. Other factors, such as cost, availability, and local experience may influence the decision to use these tests to screen for carotid artery atherosclerosis that may respond to surgery.
