PURPOSE To determine the efficacy of high-resolution MR angiography for the prospective
diagnosis of ruptured aneurysms in acute subarachnoid hemorrhage. METHODS We used 3 …

Magnetic resonance (MR) imaging of subarachnoid hemorrhage (SAH) due to a ruptured
aneurysm has been evaluated in relation to CT findings on 30 patients. In the acute stage …

Objectives: To determine the diagnostic accuracy of magnetic resonance angiography
(MRA) compared to intra-arterial digital subtraction angiography (DSA) in detection of …

We report preliminary experience with the use of magnetic resonance angiography (MRA) in
the assessment of intracranial aneurysms. The aims of the study were to confirm that …

Background Magnetic resonance angiography (MRA) has been evaluated for the detection
of unruptured intracranial aneurysms with favorable results at 3 Tesla (3 T) and with similar …

Previous reports demonstrated that Magnetic Resonance Angiography (MRA) is a reliable
means of diagnosing intracerebral aneurysms. However, in these early studies MRA was …

PURPOSE Our goal was to determine the accuracy of MR angiography at 0.5 T for the
diagnosis of intracranial aneurysms. METHODS We retrospectively studied 140 patients, 70 …

We evaluated contrast-enhanced MR angiography (MRA) for the identification of recently
ruptured cerebral aneurysms. We studied 23 aneurysms in 18 patients (age range 34–72 …

There is doubt as to whether acute haemorrhage is visible on MRI. We carried out MRI
within 6 h of symptom onset on five patients with minor (low Hunt and Hess grades 1 or 2) …

In order to evaluate the sensitivity and specificity of magnetic resonance angiography (MRA)
in spontaneous subarachnoid haemorrhage, 14 patients with recent haemorrhage verified …
