Detection of Cerebral Aneurysm in Cerebral Arteries Following Non-Invasive CT Angiogram

Abstract

Background: Cerebral aneurysm is the basic cause of sub-arachnoid hemorrhage; Computed tomographic angiogram is the non-invasive approach to diagnose aneurysm by reconstructing the image in 3D dimension making it possible to locate the aneurysm and differentiate it from other arteries. Objective: Focus of this study was to investigate the accuracy of CTA to detect the aneurysm, its type, location and size. Material and method: Data of 50 patients was taken retrospectively with cost-benefit approach that undergoes non-invasive CTA through Aquilion 64-slices CT machine under post-processing work station. Results: This retrospective study is taken with 50 patients, with a 38 percent positive predictive value and a 62 percent negative predictive value, multi-slice CT properly revealed substantial aneurysm in 19 of 50 cases. Conclusion: 64-slices CT provides high diagnostic accuracy for detecting the aneurysm in cerebral arteries with a non-invasive angiogram procedure.
