In this study, we demonstrated the efficacy of the thick slice-basal ganglia pCASL (TB-pCASL) for acute ischemic stroke. The limited scan range and selection of thick slice retain signal noise to ratio (SNR) even in approximately 1min scan. TB-pCASL can rapidly estimate an ischemic region corresponding occlusion-stenosis region, and to combine with DWI can depict penumbra within 2min. TB-pCASL is reliable and useful tool for diagnosis of acute ischemic stroke in the emergency medical field.
