BACKGROUND AND PURPOSE: Acute SAH is reportedly associated with rebleeding from
aneurysms, and recent advances in imaging technology allow us to visualize active …

Computed tomographic angiography (CTA) is being increasingly utilized in the non-invasive
diagnosis of aneurysmal subarachnoid hemorrhage (SAH). There are emerging reports of …

Objective For patients with subarachnoid hemorrhage (SAH), computed tomography
angiography (CTA) has been the first imaging modality for aneurysm detection. We evaluate …

BACKGROUND AND PURPOSE: CTA is becoming the frontline modality to reveal
aneurysms in patients with SAH. However, in about 20% of SAH patients no aneurysm is …

Background Computed tomography (CT) perfusion has been studied as a tool to predict
delayed cerebral ischemia (DCI) and clinical outcome in spontaneous subarachnoid …

Background: In some cases of spontaneous subarachnoid hemorrhage (SAH), the cause of
bleed remains obscure on initial evaluation. These patients may harbor structural lesions …

BACKGROUND The optimal diagnostic evaluation for patients with angiographically
negative subarachnoid hemorrhage (AN-SAH) remains controversial. OBJECTIVE To …

ABSTRACT PURPOSE To evaluate the utility of computed tomographic angiography (CTA)
as the primary diagnostic investigation in patients with spontaneous subarachnoid …

Background Perfusion computed tomography (CT) is a rapid technique that allows the
measurement of acute disturbances in local and global cerebral blood flow in patients …

Objective: To determine the sensitivity of the initial new‐generation CT (NGCT) scan
interpretation for detection of acute nontraumatic subarachnoid hemorrhage (SAH) and to …
