【摘要】 目的:评价磁共振(MRI)成像对主动脉夹层(aortic dissection,AD)的诊断价值。方法:分析30例AD的MRI表现,所有病例均在心电门控下行自旋回波(SE)序列和MRI电影(cine MRI)扫描。结果:30例夹层的起始部位、病变范围、真假腔血流情况、内膜片均显示清晰。20例破口显示清晰,17例示主动脉扩张,7例有附壁血栓形成。结论:MRI作为无创伤性检查,能准确识别主动脉夹层的内膜瓣、真假两腔、病变范围且能较满意的显示管腔扩张及附壁血栓等并发症。更多还原

【Abstract】 Objective:To evaluate the clinical value of MRI in the diagnosis of aortic dissection.Methods: The MRI manifestations in 30 cases of aortic dissection were analyzed retrospectively. MRI and Cine MRI were performed on all patients.Results:MRI clearly showed an intimal flap, a double lumen, site and range in all 30 patients. The site of intimal tear was located in 20 cases. aortic dilation was demonstrated in 17 cases and thrombus formation in the false lumen in 7 cases. Conclusion: As a non-invading imaging method, MRI can demonstrate the site, range and complications of aortic dissection, it is very valuable in the diagnosis of aortic dissection.更多还原
