Decrease of Hyperintense Vessels on Fluid-Attenuated Inversion Recovery Predicts Good Outcome in t-PA Patients.
BACKGROUND AND PURPOSE Hyperintense vessels (HV) detected on fluid-attenuated inversion recovery (FLAIR) in patients with acute ischemic stroke (AIS) indicate cerebral hypoperfusion. However, the clinical meaning of changes in HV is yet to be clarified. Here, we investigated serial changes to HV in patients with AIS who received tissue plasminogen activator (t-PA) therapy. METHODS We studied ...
متن کاملFluid-Attenuated Inversion Recovery Hyperintense Vessels in Posterior Cerebral Artery Infarction
BACKGROUND Fluid-attenuated inversion recovery hyperintense vessels (FHVs) are known to reflect stagnant or slow blood flow within the cerebral artery. FHVs are frequently observed in patients with acute cerebral infarction accompanied by arterial occlusion or significant stenosis of the anterior cerebral circulation. However, FHVs have not been studied in the context of posterior cerebral circ...
متن کاملHyperintense vessels on acute stroke fluid-attenuated inversion recovery imaging: associations with clinical and other MRI findings.
BACKGROUND AND PURPOSE Hyperintense vessels (HVs) have been observed in fluid-attenuated inversion recovery imaging of patients with acute ischemic stroke and been linked to slow flow in collateral arterial circulation. Given the potential importance of HV, we used a large, multicenter data set of patients with stroke to clarify which clinical and imaging factors play a role in HV. METHODS We...
متن کاملHyperintense vessel sign on fluid-attenuated inversion recovery MR imaging is reduced by gadolinium.
The HVS on FLAIR imaging is a useful marker of acute ischemic stroke. We investigated whether prior administration of gadolinium-based contrast hindered detection of this sign on images from subjects with acute nonlacunar ischemic stroke <4.5 hours after onset. Both blinded and comparative unblinded analyses showed significantly reduced HVS detection on postcontrast images. We suggest that asse...
متن کاملAngiography reveals that fluid-attenuated inversion recovery vascular hyperintensities are due to slow flow, not thrombus.
BACKGROUND AND PURPOSE Fluid-attenuated inversion recovery (FLAIR) vascular hyperintensities (FVH) are commonly encountered on MR imaging studies performed shortly after the onset of acute ischemic stroke. Prior reports have speculated regarding the pathogenesis of this finding, yet definitive correlative angiographic studies have not been performed. We studied the pathophysiologic and hemodyna...
