摘要
目的评价磁共振血管造影(magnetic resonance angiography,MRA)对主动脉夹层的诊断价值。方法回顾性分析73例主动脉夹层患者MR血管造影Express序列和RF-FAST序列的图像,将MRA检查结果与外科手术或介入治疗结果比较。结果 73例主动脉夹层中包括DeBakeyⅠ型24例、Ⅱ型6例、Ⅲ型43例。MRA对主动脉夹层分型、范围、真假腔显示的敏感性和特异性均为100%,诊断内膜破口的敏感性94.74%,特异性100%,诊断主动脉分支血管受累的敏感性91.49%,特异性92.31%。结论 MRA能准确、无创地诊断主动脉夹层,为临床选择合理的治疗方案提供重要依据。
Objective：To evaluate the value of magnetic resonance angiography （MRA） in diagnosing aortic dissection.Materials and Methods：We retrospectively analyzed MRA findings of 73 aortic dissection （AD） patients.Express and RF-FAST were used in the MR examination.The results were compared with the findings of surgery or DSA.Results：Seventy-three AD patients including DeBakey type Ⅰ24 cases,DeBakey type Ⅱ 6 cases,DeBakey type Ⅲ 43 cases.Both the sensitivity and the specificity of the presence and the differentiation of aortic dissection were 100%.The sensitivity of the localization of intimal tears was 94.74%,but the specificity was 100%.The sensitivity of the involvement of arch branches was 91.49%,but the specificity was 92.31%.Conclusion：The aortic dissection can be diagnosed by MRA accurately and non-invasive.MRA can provide more useful information to clinical treatment.
