动脉粥样硬化(atherosclerosis,AS)是临床急性缺血综合征的主要病因。近年来,大量研究资料表明,临床急性缺血综合征的发生主要取决于AS斑块的成分,而不是血管的狭窄程度[1,2]。MR I由于其多参数、多平面成像的优势以及固有的高软组织分辨率和分辨组织化学成分的能力,使其在AS病 Atherosclerosis (AS) is the main cause of clinical acute ischemic syndrome. In recent years, a large number of research data show that the occurrence of clinical acute ischemic syndrome depends mainly on the composition of the AS plaque, not the degree of vascular stenosis [1,2]. Due to its multi-parameter, multiplanar imaging advantages and its inherent high-soft tissue resolution and ability to resolve histochemical components, MR I has been implicated in AS disease
