The clinical significance of arterial transit artifact on arterial spin labeling in patients with acute ischemic stroke

Arterial spin labeling (ASL) is a noninvasive magnetic resonance imaging (MRI) technique used to assess brain perfusion quantitatively in humans. Many studies have reported the safety and utility of ASL in acute ischemic stroke (AIS); however, few reports have investigated the clinical significance of arterial transit artifact (ATA) in AIS. In this report, we focus on the utility of ATA in AIS.
