摘　　要：目的探讨磁共振成像(MRI)检查颈动脉粥样硬化斑块成分、类型与缺血性脑病的相关性。方法 100例颈动脉粥样硬化斑块患者,按照脑缺血性症状分为有症状组及无症状组,每组50例,评估斑块MRI结果与临床症状的相关性。结果两组血管在管腔狭窄程度、纤维帽的完整性和斑块是否有出血方面比较差异均有统计学意义(P<0.01),在斑块钙化、疏松间质(LM)的出现率上比较差异无统计学意义(P>0.05)。结论颈动脉粥样硬化斑块的性质和急性脑梗死的发生密切相关,MRI检查对于预测缺血性脑血管事件具有重要意义。Objective To investigate magnetic resonance imaging （MRI） in detection of component and type of carotid atherosclerotic plaque, along with correlation of ischemic encephalopathy. Methods A total of 100 patients with carotid atherosclerotic plaque were divided by their cerebral ischemic symptoms into symptomatic group and asymptomatic group, and each group contained 50 cases. Correlation between plaque MRI results and clinical symptoms was evaluated. Results There were statistically significant differences of lumen stenosis degree, completeness of fibrous cap, and hemorrhage of plaque between the two groups （P〈0.01）, while the difference of incidences of plaque calcification and loose mesenchyme had no statistical significance （P〉0.05）. Conclusion There is a close correlation between quality of carotid atherosclerotic plaque and occurrence of acute cerebral infarction. MRI examination contains important value for predication of ischemic cerebrovascular events.
