APPLICATION OF 128 SLICE MDCT ANGIOGRAPHY IN EVALUATION OF NON TRAUMATIC SUBARACHNOID HEMORRHAGE.

Abstract

Background : Subarachnoid hemorrhage(SAH) is a subtype of cerebrovascular 
accident.It can be traumatic or non traumatic. Whenever SAH is diagnosed on initial 
non contrast computed tomography(CT) ,the next step would be CT Angiography 
due to being non-invasive and easily performable even though digital subtraction 
angiography (DSA) is still the gold standard.Objectives : To analyze the etiology of 
non traumatic SAH in MDCT Angiography .
