区域性动脉自旋标记在缺血性脑血管病中的应用进展

Advances in Application of Territorial Arterial Spin Labeling in Ischemic Cerebrovascular Disease

区域性动脉自旋标记(territorial ASL,t-ASL)是一项新型的磁共振灌注技术,不同于3D-ASL的非特异性全脑灌注,t-ASL可选择性标记感兴趣动脉以判断单支血管的血流灌注情况。在缺血性脑血管病临床管理中,t-ASL可应用于责任供血动脉判断、侧支循环等脑供血代偿评估及围手术期管理等,本文就t-ASL在以上这些方面的临床应用研究进展进行了综述。

Territorial ASL(t-ASL)is a novel magnetic resonance perfusion technique,different from 3D-ASL,it can label the artery of interest to show the specific perfusion area and further evaluate the state of cerebral blood flow.In the clinical management of ischemic cerebrovascular disease,t-ASL can be applied in several aspects such as culprit artery identification,collateral circulation assessment,perioperative management and etc.Thus this article reviewed the advances in the application of t-ASL in the above aspects.
