摘要
目的评价ＭＲＩ对主动脉夹层的定性诊断和分型的价值及对临床治疗的指导作用。方法分析３２例主动脉夹层的ＭＲＩ影像资料，并与彩色多普勒超声（ＣＤＥ）对照。其中１８例手术病理证实，１４例造影证实。结果主动脉夹层ＭＲＩ表现为典型的真假腔和内膜片，定性准确率为９２７％，ＣＤＥ为６０９％，分型符合率ＭＲＩ为９３８％，ＣＤＥ为４３８％，ＭＲＩ明显优于ＣＤＥ（Ｐ＜０．０５）。结论ＭＲＩ是诊断主动脉夹层准确、全面、无创和首选的影像学检查方法。
Purpose To evaluate the MRI value of definitive diagnosis and typing as well as its roles to
clinical management with aortic dissection (AD). Methods The MRI findings were analyzed and
compared with that of color doppler echocardiography (CDE) in 32 patients proved by surgical
exploration in 18 cases and aortography in 14 cases. Results The MRI typical appearences
were the true and false lumina and the intimal flap of AD. The accuracy of MRI and CDE was 92.
7%, 60.9% respectively in characterizing AD. For determining AD type, the ratio MRI conformed
by operation and aortography amount to 93.8% (CDE 43.8%), MRI was superior to CDE
significantly ( P <0.05).Conclusion MRI is an accurate, comprehensive, non invasive medical
imaging technique and can serve as an initial imaging modality for AD diagnosis. [
