| 目的 通过和彩超及手术病理的对照分析,评价MRI对主动脉夹层的诊断价值。方法 回顾性分析了17例经我院手术病理证实的主动脉夹层动脉瘤,每例术前均行MRI及彩超检查。结果 ①16例MRI清晰显示了主动脉内膜瓣及由其分隔的真假腔, MRI诊断的手术符合率为94.1%(16/17),术前彩超诊断符合率同样为94.1%(16/17)。②MRI及彩超分型的手术符合率分别为94.1%(16/17)及70.6%(12/17)。③主动脉弓分支受累3例,MRI图像上全部得以显示, |

| Purpose To evaluate the diagnostic importance of MRI in aortic dissection through comparison with color echocardiography and surgical pathology. Methods 17 cases of aortic dissection proved by surgical pathology were analyzed retrospectively. Each case underwent MRI and color echocardiography examination before operation. Results ①MRI and color echocardiography depicted an intimal flap and a double lumen in 94.1%(16/17) patients respectively. ②MRI classification coincided well with the operative findings in 94.1%(16/17) of cases while color echocardiography in 75%(9/12). ③MRI demonstrated the major aortic branches involvement in all 3 cases and color echocardiography only in 1case. ④In the 7 cases that complicated with aortic aneurysm, both MRI and color echocardiography coincided well with the operative findings in 100% of cases. ⑤To complicated aortic regurgitation, the demonstration rate of MRI was lower than that of color echocardiography(33.3% verse 85.7%). ⑥To the site of intimal tear, both had a lower demonstration rate(11.8% and 17.6% respectively). Conclusion MRI plays an important role in the diagnosis of aortic dissection and is better than color echocardiography in demonstrating the site and extent of dissection and the involvement of major aortic branches and there is limitation in demonstrating the entry tear and aortic regurgitation. |
