BACKGROUND AND PURPOSE: Early detection of arterial occlusion and perfusion
abnormality is necessary for effective therapy of hyperacute cerebral ischemia. We …

Background: Fluid-attenuated inversion recovery (FLAIR) sequences may reveal
hyperintense vessel signals (HVS) at the acute stage of cerebral ischemia. The aim of this …

BACKGROUND AND PURPOSE: Fluid-attenuated inversion recovery (FLAIR) vascular
hyperintensities (FVH) are commonly encountered on MR imaging studies performed shortly …

Background and purpose Diffusion–weighted magnetic resonance (MR) imaging (DWI), and
three–dimensional (3D) time–of–flight (TOF) MR angiography (MRA), are highly sensitive for …

BACKGROUND AND PURPOSE: In acute ischemic stroke, whether FLAIR vascular
hyperintensities represent good or poor collaterals remains controversial. We hypothesized …

Background and Purpose—Hyperintense vessels (HVs) have been observed in fluid-
attenuated inversion recovery imaging of patients with acute ischemic stroke and been …

Objective: To describe hyperintense vessels sign (HVS) in patients with acute stroke on fluid-
attenuated inversion recovery (FLAIR) MRI and determine its clinical significance and utility …

Background: Fluid-attenuated inversion recovery (FLAIR) hyperintensity within an acute
cerebral infarct may reflect delayed onset time and increased risk of hemorrhage after …

In the hyperacute phase of stroke, occluded vessels can be seen as high signal on fast-
FLAIR images or as absence of flow-related enhancement in maximum-intensity projection …

Background and Purpose—In patients with acute stroke, the intensity of a fluid-attenuated
inversion recovery (FLAIR) lesion in the region of diffusion restriction is associated with time …
