摘要 目的探讨MRI诊断颈动脉易损斑块的准确性。方法对30例颈动脉内膜剥脱术(CEA)患者术前行MRI颈动脉管壁检查,采用SIEMENS Avanto 1.5T MRI,检查序列包括3D TOF、T1WI、T2WI、T2-TSE及增强T1WI扫描,对引起斑块不稳定的主要成分(纤维帽、脂质坏死核心、斑块内出血、钙化等)进行分析,并与CEA取出的斑块病理结果进行对照。结果 MRI检查共发现双侧颈动脉48支粥样硬化斑块,CEA取出31支斑块。MRI诊断斑块内脂质坏死、斑块内出血、钙化的敏感度和特异度分别为92.5%、100%,90.0%、90.0%,96.6%、100%;与病理结果的一致性系数Kappa值分别为0.763、0.729、0.783。结论 MRI对诊断易损斑块内脂质坏死核、纤维帽、斑块内出血、钙化等成分具有较高的敏感度和特异度,能为临床外科手术方式及内科治疗提供影像学依据。
