BACKGROUND AND PURPOSE: FLAIR-hyperintense vessels are known to be a sign of
sluggish collateral blood flow in hemispheric vessel occlusion. Additionally, they seem to …

Background A hyper-intense vessel sign on fluid attenuated inversion recovery magnetic
resonance imaging (FHV) represents slow blood flow in the cerebral arteries. Purpose To …

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 …

Background: Hyperintense vessels (HV) on fluid-attenuated inversion recovery imaging are
frequently observed in acute ischemic stroke patients. However, the exact mechanism and …

Purpose: Hyperintense vessels (HVs) on fluid-attenuated inversion recovery (FLAIR)
imaging are associated with the leptomeningeal collateral circulation in cases of arterial …
