【摘要】 目的探讨MRI对主动脉夹层的诊断与临床指导价值。方法对11例主动脉夹层患者的MRI资料进行回顾性分析。结果按照Stanford分型:A型7例,B型4例;按照De Bakey分型:I型6例,Ⅲ a型4例,Ⅲb型1例。11 例均可见主动脉内膜片及其被分隔的真假腔,共累及9条分支大血管。结论 MRI能够对主动脉夹层作出快速、安全的诊断,并为临床治疗提供详尽、可靠的信息,是主动脉夹层的首选无创性检查方法。更多还原

【Abstract】 Objective To access the diagnostic and clinical value with magnetic resonance imaging in aortic dissection. Methods To retrospectively analyze the MRI appearance of aortic dissection in 11 cases. Results 11 cases were classified with Stanford type A,B into 7,4, they were classified with De Bakey type I , II a, III b into 6, 4 and 1. The intimal flap separating the true and false lumens could be clearly displayed. 9 major aortic branches were involved.Conclusion MRI could diagnose the aortic dissection rapidly and safely, and provide elaborate and trusty information for clinical therapy. It is a preferred, noninvasive method in diagnosing aortic dissection.更多还原
