Abstract: Objective To evaluate the relationship between fluid-attenuated inversion recovery (FLAIR) vascular hyperintensity (FVH) and early ischemic lesion recurrence (follow-up diffusion-weighted imaging [FU-DWI] [+]) in patients with lesion-negative TIA. Methods We recruited consecutive patients with lesion-negative… read more here.

DOI: 10.2147/ijgm.s371894
Abstract: Purpose We aimed to investigate the prevalence of fluid-attenuated inversion recovery (FLAIR) vascular hyperintensities (FVHs) and the clinical–radiological correlation in transient ischemic attack (TIA) patients. Materials and Methods We performed a retrospective analysis of TIA… read more here.

DOI: 10.3174/ajnr.a5431
Abstract: The authors evaluated 244 consecutive patients eligible for reperfusion therapy with MCA stroke and pretreatment MR imaging with both FLAIR and PWI. The FLAIR vascular hyperintensity score was based on ASPECTS, ranging from 0 (no… read more here.

DOI: 10.3174/ajnr.a6142
Abstract: BACKGROUND AND PURPOSE: FLAIR vascular hyperintensity has been recognized as a marker of collaterals in ischemic stroke, but the impact on outcome is still controversial. We hypothesized that the association between FLAIR vascular hyperintensity and… read more here.

FLAIR Vascular Hyperintensities as a Surrogate of Collaterals in Acute Stroke: DWI Matters
Sign Up to like & getrecommendations! Published in 2022 at "American Journal of Neuroradiology"
DOI: 10.3174/ajnr.a7733
Abstract: BACKGROUND AND PURPOSE: FLAIR vascular hyperintensities are thought to represent leptomeningeal collaterals in acute ischemic stroke. However, whether all–FLAIR vascular hyperintensities or FLAIR vascular hyperintensities–DWI mismatch, ie, FLAIR vascular hyperintensities beyond the DWI lesion, best… read more here.
