BACKGROUND AND PURPOSE: In acute stroke with proximal artery occlusion, FLAIR
vascular hyperintensities observed beyond the boundaries of the cortical lesion on DWI …

Background and purpose To investigate the relation between DWI-PWI mismatch and FLAIR-
hyperintense vessel (FHV) sign and their influence on the prediction of the infarct growth in …

Objectives We tested whether FLAIR vascular hyperintensities (FVH)–DWI mismatch could
identify candidates for thrombectomy most likely to benefit from revascularization. Methods …

Abstract Background and Purpose Ischemic diffusion‐weighted imaging‐fluid‐attenuated
inversion recovery (DWI‐FLAIR) mismatch may be useful in guiding acute stroke treatment …

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

The value of fluid-attenuated inversion recovery vascular hyperintensity (FVH)-diffusion-
weighted imaging (DWI) mismatch in predicting outcome with acute stroke is unclear. We …

Background and Purpose—Fluid-attenuated inversion recovery vascular hyperintensities
(FVH) beyond the boundaries of diffusion-weighted imaging (DWI) lesion (FVH-DWI …

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

Background: Hyperintensity of distal vessels on FLAIR-MRI has been associated with a
higher grade of arterial collaterals and a smaller infarct volume in acute stroke patients. No …

ABSTRACT BACKGROUND AND PURPOSE Distal hyperintense vessels (DHV) on MRI
FLAIR sequences in acute brain ischemia are thought to represent leptomeningeal collateral …
