MRI和经阴道超声对早期瘢痕妊娠的临床诊断效果比较

目的比较阴道超声与核磁共振在剖宫产后瘢痕妊娠诊断中的价值。方法回顾性分析2016年1月至2018年1月41例剖宫产后瘢痕妊娠患者的临床资料,患者剖宫产前均经阴道超声与核磁共振成像检查。以手术结果为标准,比较经阴道超声与核磁共振成像在瘢痕妊娠中的灵敏度。结果41例患者中经阴道超声者检出34例,灵敏度82.93%,漏诊率17.07%;经MRI检出者40例,灵敏度97.56%,漏诊率2.44%.在CSP诊断中,MRI的灵敏度明显高于经阴道超声检查(P<0.05).结论MRI对剖宫产后瘢痕妊娠的总体诊断准确率高于阴道超声,临床上可以作为阴道超声检查的有效补充.

Objective To compare the value of vaginal ultrasound and nuclear magnetic resonance imaging in the diagnosis of scar pregnancy after cesarean section. Methods A retrospective analysis of 41 patients with post-cesarean scar pregnancy was performed in the hospital. All patients underwent vaginal ultrasound and MRI before cesarean section. The surgical outcome was used as a standard to compare the detection rate and missed diagnosis rate of transvaginal ultrasound and MRI in caesarean scar pregnancy examination. Results Among 41 patients, 34 were detected by transvaginal ultrasound, the sensitivity was 82.93%, the missed diagnosis rate was 17.07%, 40 by MRI, the sensitivity was 97.56%, the missed diagnosis rate was 2.44%. Statistical results showed that the sensitivity of MRI in the diagnosis of CSP was significantly higher than that of transvaginal ultrasound ( P<0.05 ). Conclusion The overaD diagnostic accuracy of MRI for scar pregnancy after cesarean section is higher than that of transvaginal ultrasound, which can be used as an effective complement to transvaginal ultrasound in clinical practice.
