| 目的 以造影剂增强MRA(CE-MRA)为参照,评价非增强MRI检查方式在诊断主动脉病变的意义。方法 17例主动脉病变患者,非增强MRI检查采用亮血对比的FIESTA电影序列和黑血对比的双反转或者三反转FSE序列,CE-MRA采用Gd-DTPA增强三维TOF序列,比较两种检查方式对病变的诊断和解剖细节的显示效果。结果 主动脉夹层7例,动脉瘤7例,降主动脉岬部缩窄2例,非增强MRI和CE-MRA诊断一致;主动脉弓粥样硬化穿通性溃疡1例只能由非增强MRI做出诊断;CE-MRA能显示病变的整体观,而非增强MRI在显示血栓形成和血流动态方面比CE-MRA有优势。结论 非增强MRI对主动脉病变的诊断具有与CE-MRA同样重要的作用,两者显示的信息可以互相补充,建议纳入MRA的常规内容。 |

| Objective To evaluate the application of non-contrast MRI examination MRI in diagnosing aortic diseases referred to the contrast-enhanced MRA (CE-MRA). Methods Seventeen patients with suspected aortic diseases were examined using both CE-MRA and non-contrast MRI. The non-contrast MRI examination included FIESTA cine sequence which were bright blood contrast and double or triple inversion recovery FSE which was black blood contrast. CE-MRA was acquired using Gd-DTPA enhanced three-dimensional TOF sequence. The diagnostic accuracies and the anatomical details on non-contrast MRI and CE-MRA were compared. Results The non-contrast MRI and CE-MRA were consistent on 7 cases of aortic dissection, 7 cases of aneurysm and 2 cases of descending aortic coarctation. 1 case of aortic atherosclerotic penetrating ulcer could be diagnosed only on non-contrast MRI. CE-MRA had the advantage in showing the global view of the lesions while non-contrast MRI had advantageous in revealing thrombosis and blood flow dynamics. Conclusion Both the non-contrast MRI and CE-MRA were essential for the diagnosis of aortic diseases, which could provide complimentary to each other. It was recommended to be included as a routine in MRA protocol. |
