摘要
动脉自旋标记法（ASL）是一种新的无创性磁共振灌注成像方法，使低灌注区在脑组织中可见及量化，并且不需要使用对比剂。在缺血性脑血管病患者，应用ASL灌注成像帮助评估血流动力学功能损伤，用以观察患者临床表现及监测病情演变，同时指导治疗方案。现就ASL技术及在脑血管病中的应用研究进行综述，以指导临床。
Arterial spin labeling （ASL） is a noninvasive magnetic resonance perfusion imaging method for visualizing and quantifying whole-brain perfusion, and does not require to use exogenous contrast agents. In patients with ischemic cercbrovascular disease, ASL MR-showed perfusion and cerebrovascular reactivity can help assess the hemodynamic dysfunction for monitoring clinical manifestations and disease evolution, so as to guide the medicinal and surgical treatment. This paper reviewed ASL technology and its application in cerebrovaseular disease to guide the clinical treatment.
