BACKGROUND AND PURPOSE: CT angiography is increasingly used to evaluate patients
with nontraumatic subarachnoid hemorrhage given its high sensitivity for aneurysms. We …

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 …

Introduction Ruptured intracranial aneurysms are responsible for over 90% of cases of
spontaneous subarachnoid hemorrhage (SAH). Conventional digital subtraction …

Background Computed tomography angiography (CTA) is today the primary method for the
detection of intracranial aneurysms. The technique has evolved considerably during the last …

Purpose: To evaluate the usefulness of CT angiography (CTA) in the detection of intracranial
aneurysms in patients with acute subarachnoid hemorrhage (SAH). Material and Methods …

PURPOSE: To evaluate if computed tomographic (CT) angiography can replace digital
subtraction angiography (DSA) for aneurysm detection and as preoperative work-up in …

Even if acute subarachnoid hemorrhage (SAH) accounts for only 5% of strokes, its diagnosis
is very important because its clinical consequences can be tragic. Recent technological …

Object The yield of CT angiography (CTA) and MR angiography (MRA) in patients with
subarachnoid hemorrhage (SAH) who have a negative initial catheter angiogram is currently …

Purpose. The leading cause of a nontraumatic subarachnoid haemorrhage is rupture of an
intracranial aneurysm. The aim of this study was to assess the usefulness of multislice …
