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 .
