摘　　要：目的:探讨MRI对主动脉瘤伴主动脉夹层的诊断价值及其表现。材料与方法:10例主动脉瘤伴主动脉夹层病人于临床症状出现后1天至360天接受了磁共振成像,其中男性8例,女性2例,年龄25～63岁(平均43岁)。5例呈急性发病,而另5例为慢性发病。半数以上的病人有高血压病史。对所有病人的磁共振成像,均采用了Siemens超导机Magnetom Impact 1.0T。结果:10例病人按受累部位分别归类为DeBakey Ⅰ型1例,Ⅱ型2例,以及Ⅲ型7例。结论:磁共振成像技术对主动脉瘤伴主动脉夹层病人的诊断,具有其他方法所不能比拟的精确性。Purpose: To explore the diagnostic usefulness of MR imaging technique and its characteristic findings for the aortic aneurysm complicated with aortic dissection. Materials and Methods: Ten patients with aortic aneurysm complicated with aortic dissection underwent MR imaging within 1 - 360 days after onset of clinical symptoms. 8 patients were male and 2, female with age ranged between 25 - 63 years (mean, 43 old years) . 5 patients were acute onset but other 5 patients were chronic pathogeny. More than half patients had history of hypertension. MR imaging in all patients used Siemens superconductor Magnetom Impact 1.0 T. Results: One, two and seven patients were classifyed to DeBakey type Ⅰ, Ⅱ and Ⅲ, respectively. Conclusion: MR imaging technique in the diagnosis of patients with aortic aneurysm and aortic dissection has higher accuracy which is superior to other methods.
