高分辨磁共振血管壁成像在颅内动脉狭窄病因鉴别中的研究进展

Research Progress of High-resolution Magnetic Resonance Vessel Wall Imaging in the Identification of Intracranial Arterial Stenosis Etiology

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。

Abstract: 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.
