Angiographic Detection of Carotid Plaque Ulceration:Comparison with Surgical Observations in a Multicenter Study Stroke 25:1130-1132, Streifler,J.Y.,et al, 1994 See this aricle in Pubmed Article Abstract Sensitivity and specificity of detecting ulcerated plaques were 45.9%and 74.1%respectively.The positive predictive value of identifying an ulcer was 71.8%.These results remained unchanged with differing degrees of carotid stenosis and were confirmed by analyses based on receiver operating characteristic(ROC)methodology.The area under the ROC curve(A), was estimated to be 0.61(95%confidence interval,0.55 to 0.67).These observations from a multicenter study confirm that little agreement exists between angiography and surgical observation in detecting carotid plaque ulceration.
