颈动脉粥样硬化与缺血性卒中的发生关系密切,易损斑块是缺血性卒中发生的主要原因。MRI尤其是高分辨率MRI是目前研究颈动脉粥样硬化易损斑块的主要热点。文章阐述了动脉粥样硬化斑块类别、MRI对颈动脉粥样硬化易损斑块诊断分析技术,从扫描序列选择、增强扫描和分子影像技术、弥散加权成像到图像分析,综述识别易损斑块的特点。最后提出MRI能对颈动脉粥样硬化斑块内成分进行早期准确的分析,为临床提供早期治疗,降低脑血管事件的发生率和病死率。
Carotid atherosclerosis and ischemic stroke are closely related to the occurrence of vulnerable plaque is the main cause of ischemic stroke. MRI, especially high-resolution MRI, is currently the main focus of the study of vulnerable plaque in carotid atherosclerosis. This article describes the classification of atherosclerotic plaque and the diagnostic technique of MRI for vulnerable plaque of carotid atherosclerosis. From scanning sequence selection, enhanced scanning and molecular imaging techniques, diffusion weighted imaging to image analysis, Features of the block. Finally, MRI can make early and accurate analysis of the components in carotid atherosclerotic plaque, providing early treatment for clinical treatment and reducing the incidence of cerebrovascular events and mortality.
