摘　　要：颅内动脉粥样硬化性疾病(intracranial atherosclerotic disease,ICAD)具有高发病率及高复发率。近年来随着磁共振成像技术的快速发展,新兴扫描方案及技术手段层出不穷,从管腔、管壁、脑组织灌注及血流动力学等多角度对ICAD的多模态方式也成为国内外脑卒中研究的热点。本文综合了目前临床常用的MRI技术,从形态到功能对ICAD研究进展进行综述,主要探讨各种技术在诊断管腔狭窄、易损斑块特征以及脑组织灌注等方面的能力及差异,为临床医师提供ICAD形态和功能方面的信息,可作为诊断、鉴别诊断、风险预测和治疗评估的参考。Intracranial atherosclerotic disease(ICAD)has a high morbidity and recurrence rate.With the rapid development of MRI technologies and applications,multimodal MRI provides multiple valuable information on vessel lumen,vessel wall,cerebral perfusion and cerebral hemodynamics.This review integrates commonly used MRI techniques in clinical practice to discuss the recent advances in ICAD research from morphology to function,mainly focusing on the capabilities and differences of various techniques in diagnosing luminal stenosis,vulnerable high-risk plaques and cerebral perfusion,etc.,aiming to provide clinicians with information on ICAD morphology and function,as a reference for diagnosis,differential diagnosis,risk prediction,and treatment assessment.
