Intracranial Arteries:Prospective Blinded Comparative Study of MR Angiography and DSA in 50 patients Radiology 195:451-456, Klaus,W.S.,et al, 1995 See this aricle in Pubmed Article Abstract Mr angiography had a sensitivity of 100%and a specificity of 95%for detection of vessel occlusion(10 abnormalities).For detection of substantial vessel stenosis(seven abnormalities),sensitivity and specificity were both 86%;for detection of aneurysm(six abnormalities), sensitivity was 83%and specificity was 98%.Sensitivity and specificity were 100%for detection of arteriovenous malformation(three abnormalities), vessel displacement(three abnormalities),and extracranial-intracranial bypass(two abnormalities).MR angiography did not reliably demonstrate small feeding vessels of a tumor or faint residual perfusion of a thrombosed aneurysm.MR angiographic diagnosis of disease of the intracranial vasculature has high sensitivity and specificity but still is limited in comparison with intraarterial DSA.
