ACCURACY OF 16-ROW MULTISLICE COMPUTED TOMOGRAPHIC ANGIOGRAPHY FOR ASSESSMENT OF SMALL CEREBRAL ANEURYSMS

Many cases of subarachnoid hemorrhage are the result of rupture of small cerebral aneurysms. The aim of the study was to assess the diagnostic accuracy of 16-row multislice computed tomographic angiography (CTA) in detecting small cerebral aneurysms ( 0.05). Sixteen-slice CTA images show more clarity and accuracy in the relationship of aneurysms to bone structures and adjacent branch vessels.Noninvasive 16-slice CTA is sensitive enough to replace conventional DSA in the triage, diagnosis, and treatment planning in patients with small cerebral aneurysms.
