症状性大脑中动脉狭窄管壁特征的HRMRI研究

摘要

目的 应用高分辨率磁共振成像(high-resolution magnetic resonance image,HRMRI)技术研究症状性大脑中动脉粥样硬化性狭窄患者的管壁特征.材料与方法 回顾性分析127例症状性大脑中动脉(middle cerebral artery,MCA)粥样硬化性狭窄患者的临床资料和影像学资料.根据扩散加权成像(diffusion weighted image,DWI)序列分为症状组和非症状组,比较两组患者的临床基线资料和管壁斑块情况(斑块分布、形态、信号).结果 糖尿病在两组中差异具有统计学意义(χ2=23.446,P0.05). One hundred and ten plaques in 127 cases, ventral plaque was the most. Superior plaque was more in symptomatic group than asymptomatic group (χ2=4.257, P=0.039), irregular surface was significant difference in two groups (χ2=8.087, P=0.004), hyper-intensity was obvious difference in two groups (χ2=5.396, P=0.020). Conclusion: HRMRI could evaluate the wall features of atherosclerotic middle cerebral artery.
