摘　　要：目的　评价MRI对主动脉瘤的诊断价值。方法　收集我院 1994-12～ 2 0 0 0 -0 73 12例临床疑为主动脉瘤患者的MRI检查 ,其中男 172例 ,女 14 0例。两名经验丰富的放射学医师对所有图像采用双盲法分析。结果　MRI共显示了 198例主动脉瘤病变 ,其中真性动脉瘤 2 2例、假性动脉瘤 19例、主动脉夹层 12 7例 (Ⅰ型 48例 ;Ⅱ型 12例 ;Ⅲ型 67例 )、马凡综合征 2 6例及复合动脉瘤 4例。与XRA、CT及手术结果对比研究 ,MRI的敏感度为 99% ,精确度为 94%。结论　MRI完全能满足临床诊断和治疗的需要 ,可作为主动脉瘤病变的临床首选检查方法。Objective To investigate the diagnosis value of aortic aneurysm with MRI.Methods Two radiologist analysed 312 cases MRI of clinically suspected aortic aneurysm retrospectively,and screening 198 cases of aortic aneurysm,analysed by double blind method.Among these patients,there were 112 male and 87 female,aged 9 to 82 years(mean age of 50.4 years).86 cases underwent X-ray angiography(XRA) examination,and 79 cases with operation.Results The MRI showed 22 cases of ture aneurysm,19 of false aneurysm,127 of dissecting aneurysm,26 of Marfan′s syndrome and 4 of compound aneurysm.Contrast analysed the XRA,CT and operation,the sensitivity and accuracy of MRI is 99% and 94%.Conclusion The MRI is an accurate and safe method for detecting aortic aneurysm.
