Clinical significance of fluid-attenuated inversion recovery vascular hyperintensities in transient ischemic attack.
BACKGROUND AND PURPOSE Fluid-attenuated inversion recovery vascular hyperintensity (FVH) is often identified in patients with acute ischemic stroke. The purpose of this study was to determine the clinical significance of FVH in patients with transient ischemic attack (TIA). METHODS Consecutive inpatients with TIA who underwent MRI within 24 hours of symptom onset were studied. The frequency, ...
متن کاملJuxtacortical Spots on Fluid-Attenuated Inversion Recovery Images in Cryptogenic Transient Ischemic Attack
BACKGROUND AND PURPOSE Juxtacortical spots are detected frequently on fluid-attenuated inversion recovery (FLAIR) images, but have not been extensively researched in patients with transient ischemic attack (TIA). We hypothesized that juxtacortical spots on FLAIR images are partly associated with right-to-left shunt (RLS) in TIA without clear etiology. The possibility of an association between t...
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...
متن کاملFluid-attenuated inversion recovery vascular hyperintensities: an important imaging marker for cerebrovascular disease.
Vascular hyperintensities have been noted on FLAIR sequences obtained in the setting of acute stroke and intracranial steno-occlusive disease. The presence of FVHs likely represents disordered blood flow, often from collaterals distal to arterial occlusion or stenosis. As opposed to other vessel signs seen in arterial insufficiency, FVH is unique in that it does not represent thrombus, but rath...
متن کاملResponse by Kim and Ha to Letter Regarding Article, "Clinical Significance of Fluid-Attenuated Inversion Recovery Vascular Hyperintensities in Borderzone Infarcts".
BACKGROUND AND PURPOSE Fluid-attenuated inversion recovery vascular hyperintensities (FVHs) are seen in some cases with cerebral hemodynamic impairment and collateral flow. Because the worst outcomes of patients with borderzone infarcts were mainly correlated with impaired hemodynamics, the presence of FVH might provide another clue for predicting the prognosis of patients with borderzone infar...
