高分辨率磁共振血管壁成像在颅内动脉粥样硬化性疾病中的应用

Application of high-resolution magnetic resonance vessel wall imaging in intracranial atherosclerotic disease

高分辨率磁共振血管壁成像(HR-VWI)是一种具有超高分辨率的磁共振成像技术。其抑制血流信号后能清晰显示动脉粥样硬化斑块的纤维帽、脂质核心、壁内血肿及管腔狭窄情况。HR-VWI能为临床诊疗提供关键影像学信息,在动脉粥样硬化性心脑血管疾病中具有重要诊断价值。本文就HR-VWI成像原理及其在颅内动脉粥样硬化性疾病的评估、在颅内动脉夹层及动脉瘤中的应用价值、在症状性非狭窄性颅内动脉粥样硬化性疾病中的应用、在脑小动脉病变及腔隙性脑梗死中的应用与动脉粥样硬化性疾病的科学研究等方面进行综述。

High-resolution magnetic resonance vascular wall imaging(HR-VWI) is a magnetic resonance imaging technology with ultra-high resolution. By suppressing blood flow signals, it can clearly present fibrous caps, lipid cores, intramural hematomas and lumen stenosis of atherosclerotic plaques. HR-VWI provides important imaging information and has great value for clinical diagnosis and treatment in atherosclerotic cardiovascular and cerebrovascular diseases. This article reviews the imaging forming principle of HR-VWI and its clinical application with scientific research in intracranial atherosclerotic diseases.
