目的 比较产前MRI和超声在凶险性前置胎盘伴胎盘植入中的价值。方法 回顾性分析2016年1月至2017年4月期间的110例凶险性前置胎盘患者，将其产前MRI与超声检查同手术病理结果进行对比分析，比较两种方法对胎盘植入的诊断价值。结果 经手术病理证实，87例凶险性前置胎盘伴发胎盘植入，产前MRI诊断的敏感性、特异性、阳性和阴性预测值以及准确率分别为91.8%、32.0%、82.1%、50.0%、78.2%，超声的敏感性、特异性、阳性和阴性预测值以及准确率分别为47.1%、72.0%、85.1%、28.6%、52.7%。结论 对疑诊为凶险性前置胎盘的病例，产前MRI和超声诊断相互结合相互补充，有助于提高胎盘植入的诊断准确性。

Objective The aim of this study was to evaluate the role of MRI and Ultrasonography in the diagnosis of adherent placenta in pregnancies with pernicious placenta previa. Method Between January 2016 and April 2017, 110 pregnancies with placenta previa investigated by ultrasound and Doppler and then in suspected cases MRI was obtained prenatally. The ultrasonography and MRI diagnosis were compared with the ?nal pathologic or operative ?ndings or with both. Results By pathologic or operative ?ndings or both，87 pregnancies were confirmed to presence of placenta previa with adherent placenta，The sensitivity，specificity，positive predictive value，negative predictive value，accuracy of MRI and US in diagnosis of adherent placenta were 91.8%、32.0%、82.1%、50.0%、78.2% and 47.1%、72.0%、85.1%、28.6%、52.7% respectively. Conclusions Data of the present study show that the use of transabdominal color Doppler ultrasonography complemented by MRI in suspected cases improves the diagnostic accuracy in prediction of adherent placenta in pregnancies with pernicious placenta previa.
