摘　　要：颅内动脉狭窄(ICAS)导致的缺血性脑卒中,具有高致残率和致死率的特点。临床上常规检查方法包括经颅多普勒超声、CT血管造影、磁共振血管造影和X射线数字减影血管造影等,上述方法都是针对血管狭窄,不能显示血管壁病变。高分辨磁共振血管壁成像技术(HR-VWI)是一种新出现的影像学检查手段,能够无创性显示血管壁病变,对判断ICAS病变性质具有重要价值。本文针对HR-VWI在ICAS病因鉴别中的应用研究进展进行综述。Ischemic stroke caused by intracranial arterial stenosis(ICAS)is characterized by high morbidity and mortality.Conventional clinical examination methods include transcranial Doppler ultrasound,CT angiography,magnetic resonance angiography,and X-ray digital subtraction angiography.These methods are aimed at vascular stenosis and do not show vascular wall lesions.High-resolution magnetic resonance vessel wall imaging(HR-VWI)is a new imaging method that can non-invasively display vascular wall lesions and has important value in judging the nature of ICAS lesions.In this paper,the application of HR-VWI in the identification of ICAS etiology is reviewed.
