摘　　要：颅内动脉粥样硬化性病变(ICAD)是亚洲人群缺血性脑卒中和短暂性脑缺血发作的重要原因。MR血管成像(MRA)对ICAD的诊断与评估起着重要作用。7 T超高场强MR可提供超高分辨力及信噪比,能够较好地显示和评估脑血管病变,并可直接进行小血管在体成像,为ICAD的研究提供新方向。就7 T MR颅内血管成像技术在ICAD中的应用及研究进展进行综述。Intracranial atherosclerotic disease(ICAD)is a significant etiology of ischemic stroke and transient ischemic attack in Asian populations.Magnetic resonance angiography(MRA)plays a crucial role in the diagnosis and assessment of ICAD.7 T ultra-high field MR offers excellent resolution and signal-to-noise ratio,allowing for better visualization and assessment of cerebrovascular lesions.It also enables in vivo imaging of small blood vessels,offering new directions for ICAD research.This review summarizes the application and research advancements of 7 T MR intracranial vascular imaging techniques in ICAD.
