剖宫产术后子宫瘢痕妊娠诊断:阴道彩超与MRI比较

Diagnosis of Cesarean Scar Pregnancy:Comparison of Transvaginal Color Doppler Ultrasound and MRI

目的:探讨剖宫产术后子宫瘢痕妊娠诊断中阴道彩超及MRI技术的应用价值。方法:本院2010年9月—2014年9月收治的剖宫产术后子宫瘢痕妊娠患者23例纳入研究,平均年龄(30.1±5.1)岁,全部完成阴道彩超及MRI检查,其中行MRI增强检查17例。结果:阴道彩超正确诊断瘢痕妊娠18例,准确率78.3%,MRI检查全部正确诊断,准确率100%。结论:阴道彩超可以较好诊断剖宫产术后子宫瘢痕妊娠,但MRI更加准确,可以作为阴超诊断疑难时的有效补充。

Purpose： To explore the application value of transvaginal color Doppler ultrasound and MRI technology in clinical diagnosis of cesarean scar pregnancy. Methods： Twenty-three cases with uterine scar pregnancy after cesarean section in our hospital from September 2010 to September 2014 were enrolled in our study. Their average age was 30.1±5.1 years. All of them were undergone transvaginal color Doppler ultrasound and MRI examination, and enhanced MRI scan was done in 17 cases. Results： Of all these 23 definitive cesarean scar pregnancy cases, 18 cases were correctly diagnosed by transvaginal color Doppler ultrasound, diagnostic accuracy was 78.3%, 23 cases were correctly diagnosed by MRI, diagnostic accuracy was 100%. Conclusion： Transvaginal color Doppler ultrasound was effective in the diagnosis of cesarean scar pregnancy. But the effect of MRI was better than that of transvaginal color Doppler ultrasound, MRI could be a supplementary method for cases hardly to be diagnosed by transvaginal ultrasound.
