CT evaluation of subarachnoid hemorrhage: a practical review for the radiologist interpreting emergency room studies.
Radiologists working in an emergency radiology setting frequently interpret computed tomography (CT) studies of patients with suspected subarachnoid hemorrhage (SAH). This article reviews the sensitivity of CT for detection of SAH, some major patterns of SAH related to a ruptured aneurysm, and the differential diagnosis of SAH not due to aneurysmal rupture.
