| 摘 要： | 目的:探讨常规MRI结合3D CE MRA对主动脉夹层动脉瘤的诊断价值。方法:回顾分析40例主动脉夹层病例,均行常规MRI和3D CE MRA检查。结果:40例主动脉夹层动脉瘤,DeBaKeyⅠ型7例,DeBaKeyⅡ型8例,DeBaKeyⅢ甲型2例,DeBaKeyⅢ乙型23例。本组40例均显示双腔征及内膜片,25例显示破口,13例假腔内血栓形成,16例伴少量胸腔积液。结论:常规MRI结合3D CE MRA对主动脉夹层动脉瘤的显示具有一定的敏感性和特异性,对主动脉夹层动脉瘤的诊断有重要价值。

| Abstract: | Objective:To explore the value of conventional MRI combined with 3D CE-MRA in diagnosing aortic dissection.Methods:Retrospectively analysed 40 cases of aortic dissection,all cases were examined by conventional MRI and 3D CE-MRA.Results:40 cases of aortic dissection including: 7 cases of DeBakeyⅠ,8 cases of DeBakey Ⅱ,2 cases of DeBakey Ⅲ type A,23 cases of DeBakey Ⅲ type B.40 cases with double cavity sign and internal flap,25 cases with crevasse,13 cases with thrombosis in false lumen,16 cases with a few of pleural effusion.Conclusion:Conventional MRI combined with 3D CE-MRA has a certain sensitivity and specificity in displaying the aortic dissection,having important value in diagnosiing aortic dissection. |
