3D-ASL在缺血性脑血管病的研究现状与进展

Current status and progress of 3D-ASL for ischemic cerebrovascular disease

三维动脉自旋标记(3D-ASL)作为一种新兴的磁共振灌注技术,凭借其无需对比剂即可测量脑血流量的优势,近年来逐步应用于临床中,尤其对于缺血性脑血管病的诊断、疗效评价有很大帮助。本文从3D-ASL技术方面、脑血流量的影响因素以及3D-ASL在缺血性脑血管病研究现状与进展方面做一综述。

Recently, a noncontrast method of measuring cerebral blood flow（CBF） using 3D-arterial spin labeling（3D-ASL） has become feasible in the clinical setting. 3D-ASL has a great help in the diagnosis and treatment of ischemic cerebrovascular disease. This review summarizes the 3D-ASL technology, the influence factors of CBF and the current status and progress of 3D-ASL in ischemic cerebrovascular disease.
