摘　　要：颅内动脉粥样硬化性狭窄(intracranial atherosclerotic stenosis,ICAS)是缺血性卒中的主要病因之一,但主要基于狭窄程度指导血管内治疗的国际多中心临床研究均未获得阳性结果。近年来,ICAS的评价逐渐从传统解剖学(狭窄程度)转向血流动力学和斑块特征。文章就MRI在ICAS血流动力学评价方面的应用进行了综述。Intracranial atherosclerotic stenosis(ICAS)is one of the main causes of ischemic stroke,but the international multicenter clinical studies,which are mainly based on the degree of stenosis to guide endovascular treatment,have not obtained positive results.In recent years,the evaluation of ICAS has gradually transferred from traditional anatomy(degree of stenosis)to hemodynamics and plaque characteristics.This article reviews the application of MRI in the hemodynamic evaluation of ICAS.
