Fluid-Attenuated Inversion Recovery Vascular Hyperintensities in Patients with Transient Ischemic Attack

FVH signals on FLAIR images occur in patients with TIA and might correlate with clinical variables like AF and not only with large vessel occlusion. The presence of FVH in patients with TIA and AF might be a surrogate marker for a large vessel occlusion spontaneously recanalized or for impaired autoregulation in a previously ischemic vascular territory.
