Abstract Cerebrovascular disease is a disease with high morbidity, disability and mortality rates, which seriously affects the daily life of patients and is a heavy burden on families and society. Arterial spin labeling (ASL) is a magnetic resonance imaging (MRI) technology that uses the magnetic labeling of hydrogen atoms in arterial blood as tracers to noninvasively evaluate brain blood flow. ASL does not require injection of an exogenous contrast agent, and has the advantages of no radiation, simplicity and low cost. In cerebrovascular diseases, ASL can evaluate the collateral cerebrovascular circulation and abnormal perfusion of brain tissue, which can provide a reliable basis for early diagnosis and clinical decision-making. This study reviewed ASL and its application in the diagnosis, treatment and prognosis of cerebrovascular diseases.
