摘　　要：目的探讨MRI多序列扫描对动脉硬化斑块稳定性分型评估的价值。方法 220例经B超检查确诊为颈动脉狭窄患者,对血管狭窄部行MRI多序列联合检查,根据斑块在MRI不同序列表现分为A型、B型、C型、D型,评估各型斑块与脑梗死关系。结果 A型和D型斑块在急性脑梗死中发生率高于陈旧脑梗死及无梗死组,差异有统计学意义(P<0.05)。结论 MRI多序列联合检查及分型可以对颈动脉粥样硬化斑块的稳定性进行评估,为脑梗死的防治提供影像学依据。Objective To explore the value of Multi - sequence MRI scan in assessing the stability classification of atberosclerosis plaque. Methods Two hundred and twenty patients diagnosed by B uhrasonography for carotid artery stenosis, Department of Vascular Stenosis were examined by the Multi - sequence MRI scan. According to the different performance of MRI sequence, Plaque was divided into A - type （ lipid - based）, B - type （ fiber type） , C - type （ calcified）, D - type （ mixed type）, to assess the the relationship between the various types of plaque and cerebral infarction. Results Incidence of acute cerebral infarction in A - and D - type plaque were statistically significantly higher than in the old cerebral infarction and non - infarction group （ P 〈 0. 05 ）. Conclusion Multi - sequence MRI scan and classification may assess the stability of carotid atherosclerosis plaque . and provide imaging basis for the prevention and treatment of cerebral infarction.
