Three-Dimensional CT Angiography in the Detection and Characterization of Intracranial Berry Aneurysms AJNR 17:439-445, Hope,J.K.A.,et al, 1996 See this aricle in Pubmed Article Abstract Ninety-four aneurysms were found in 63 patients.Negative findings at angiography were noted in 17.Sensitivity and specificity of 3-D CTA for all aneurysms,all patients,and aneurysms 5 mm or smaller were 90.4%and 50%,98.4%and 82.4%,and 78.85 and 51.9%,respectively.Three-dimensional CTA may have a role in noninvasive screening for asymptomatic aneurysms in the general population,but caution is advocated when data obtained from symptomatic patients are extrapolated to the asymptomatic population who harbor smaller aneurysms.Also,3-D CTA may be useful as an adjunct to angiography in the characterization of berry aneurysms and in the follow- up of untreated aneurysms.
