多模式CT在评估急性缺血性卒中脑侧支循环中的应用

多模式计算机断层扫描（computed tomography，CT）包括CT平扫（non-contrast CT，NCCT）、 CT灌注成像（CT perfusion，CTP）、CT血管成像（CT angiography，CTA），可以对急性缺血性卒中后侧支 循环进行全面评估，评估脑灌注状态，了解脑侧支循环建立或开放情况，判断临床预后，在急性缺血 性卒中的诊疗过程中发挥重要的作用。本文就多模式CT在缺血性卒中中的应用进行综述，以期使患 者获益更多。

Application of Multimodal CT in the Evaluation of Collateral Circulation in Acute Ischemic Stroke

Multimodal computed tomography (CT) including non -contrast CT(NCCT), CT perfusion imaging(CTP), and CT angiography(CTA). It can comprehensively assess the collateral circulation after acute ischemic stroke, assess cerebral perfusion status, observe the cerebral collateral circulation establishment or open situation, judge the clinical outcome, and play an important role in the process of diagnosis and treatment of acute ischemic stroke. This article reviewed the application of multimodal CT in ischemic stroke, in order to bring more clinical benefits to patients.
