急性冠脉综合征常继发于易损斑块破裂后引起的血栓事件.因此,准确地评估斑块的性质、稳定性,对预防心血管事件的发生有重要的意义.现就血管内超声、光学相干断层扫描技术、多层螺旋计算机断层摄影术、磁共振成像、核素显像及血管镜等评估易损斑块的影像学检查及其相应的优缺点予以综述.“,”Acute coronary syndromes are often secondary to rupture of vulnerable plaques and subsequent thrombosis.Therefore,accurate assessment of plaque composition to determine whether it is stable or not is of great significance to prevent the occurrence of acute myocardial infarction and other related cardiovascular events.This paper reviews the intravascular ultrasound,optical coherence tomography, multislice spiral computed tomography,magnetic resonance imaging and the disadvantages of radionuclide imaging and vascular endoscopy evaluation methods and their advantages and the corresponding vulnerable plaque.
