摘要 目的采用3.0T HR-MRI成像鉴别脑动脉粥样硬化和脑动脉炎。方法收集2011-03—2015-12河南省人民医院治疗的88例脑动脉粥样硬化患者及71例脑动脉炎急性期患者;采用德国西门子TrioTim 3.0T磁共振扫描仪。结果脑动脉粥样硬化病人管壁偏心性增厚、偏心性强化占98%(86/88),显著高于脑动脉炎病人所致的偏心性增厚、偏心性强化5.6%(4/71)(χ^2=131.95,P=0.005)。脑动脉炎病人在急性期血管壁环形增厚、环形强化占94.4%(67/71),显著高于脑动脉粥样硬化病人环形增厚、环形强化发生率2%(2/88)(χ^2=131.95,P=0.005);脑动脉炎(59例)大脑中动脉的发生率显著高于脑动脉粥样硬化组(27例)(χ^2=41.387,P=0.005)。脑动脉粥样硬化组颈内动脉颅内段(29例)的发生率显著高于脑动脉炎组(5例)(χ^2=14.189,P=0.005)。结论脑动脉粥样硬化组管壁多呈偏心性增厚及偏心性强化,脑动脉炎组管壁多呈环形增厚及环形强化。脑动脉炎大脑中动脉的发生率显著高于脑动脉粥样硬化组,颈内动脉颅内段的发生率显著低于脑动脉粥样硬化组。
