PURPOSE To determine the significance of vascular enhancement in stroke patients with
and without permanent neurologic deficit. METHODS We prospectively studied two groups …

Eighty patients with a total of 82 ischemic lesions were examined with contrast-enhanced
MR imaging 1 hr to 1 month after onset of symptoms. The studies were reviewed …

MR imaging with IV administration of gadopentetate dimeglumine was performed in 89
patients with 100 clinically and radiologically documented brainstem or deep cerebral (basal …

BACKGROUND AND PURPOSE: Intravascular and parenchymal enhancement have been
detected with contrast-enhanced T1-weighted MR imaging in patients with ischemic stroke …

MR changes of cerebral ischemia have been shown to occur as early as 1-2 hr after vessel
occlusion in experimental models of stroke. However, the MR findings in the early stages of …

PURPOSE To investigate the cause and clinical significance of arterial enhancement (AE) in
contrast-enhanced T1-weighted MR examinations after acute cerebral ischemia. METHODS …

PURPOSE To determine the prevalence of major vessel occlusion in cases of acute cerebral
ischemia of the anterior circulation by using MR angiography and to assess the frequency of …

PURPOSE To determine the histologic changes associated with gadopentetate
dimeglumine enhancement on MR images in acute focal cerebral ischemia. METHODS In …

PURPOSE To determine the contribution of cranial MR angiography (MRA) for the
evaluation of patients with acute and subacute brain infarction. METHODS MR and MRA …

MR angiography (MRA) is a powerful, noninvasive diagnostic imaging technique for
examining normal and abnormal blood vessels. Initially, MRA approaches were developed …
