主题词：磁共振成像；颈动脉粥样硬化；脑梗死；不稳定斑块

中图分类号：

目的：探讨MRI检测颈动脉粥样硬化斑块的价值及斑块稳定性与脑梗塞的相关性。方法：选取患者男64例，女36例，年龄41-85岁。行颈部及头颅MRI、MRA检查。经统计学分析斑块的MRI不同分型与脑梗死发生的关系。 结果：1.100例患者MRI共检出261处粥样硬化斑块，按AHA斑块分型，各型斑块的脑梗死发生率有统计学差异(P<0.05)；2.根据狭窄程度计算I级、I级以上颈动脉狭窄和脑梗塞的相关性r=0.710（p=0.000）。结论：1.采用多对比加权的MRI序列对斑块具有准确定位及分型能力，且分析斑块的稳定性；2.颈动脉粥样硬化引起缺血性脑血管病与动脉严重狭窄有关。

Objective：To investigate the value of noninvasive imaing-magnetic resonance
imaging-in detecting the correlation between carotid atherosclerotic plaque and
the brain infarction。Methods:100 patients (male 64 and female 32 from 41-85),crotid
atherosclerotic plaques were found by us first，brain examination found by
MRI,analysis was performed to evaluate the associativity between the type of
the plaque and strok。All plaques were assessed
with distribution size,shape and the extent of the stenosis by MRI。Results: 1、216 plaques were found by MRI in 100 patients,two type of the plaque
showed significount,difference in the incidence of stroke after statistical
analysis (p<0.05) 2、Counting the relation
between II、III、IV degree of  the carotid artery and the brain
infarction,spearman index equaled to 0.710。Conclution：1、Multi sequences MR
imaging,including FSE-T1W,FSE-T2W,DIR T1W and 3D TOF can exactly locate the
plque and typing capability,It also can make analysis for the plque。2、We could  reliably identy the
morphologic features of the vulnerable plaque,The unstable plaques are well related
with the brain infarction。

Key words：MRI，Atherosclerosis，Brain infarction，unstable plaque
