Tissue perfusion and structural imaging provides important information in the evaluation of ischemic stroke. MR-fingerprinting (MRF) arterial spin labeling (ASL) is a novel noninvasive method of ASL perfusion that allows simultaneous estimation of cerebral blood flow (CBF), bolus arrival time (BAT), and tissue T1 map in a single scan of <4 minutes. Here we evaluated the utility of MRF-ASL in ischemic stroke patients in depicting hemodynamic and structural abnormalities, as well as predicting neurological deficits and disability.
