Common Carotid Artery Bifurcation:Prelim Results of CT Angio & Color-Coded Duplex Sonogr Compared with DSA AJR 168:361-365, Link,J.,et al, 1997 See this aricle in Pubmed Article Abstract Grading of stenoses on CT angiography agreed with grading of stenoses on digital subtraction angiography in 89%of cases.All high grade stenoses and occlusions revealed on CT angiography were correctly interpreted by all observers.For stenoses revealed by color-coded duplex sonography and digital subtraction angiography,observers'agreement was 75%.Two severe stenoses were incorrectly graded as occluded by the interpreter of the color-coded duplex sonograms.Also,one occluded carotid artery was misdiagnosed as moderate stenosis.Our results indicate that CT angiography is superior to color-coded duplex sonography for evaluating carotid disease and determine disease requiring surgery.CT angiography warrants further investigation in a larger group of patients.
