摘　　要：目的 探究、对比超声与磁共振成像(magnetic resonance imaging,MRI)在中期妊娠对胎盘植入的诊断价值。方法 收集广东省妇幼保健院2018年2月至2020年2月收治的64例产前检查疑似胎盘植入的中期妊娠患者的临床资料。予以所有患者彩色多普勒超声检查及MRI检查,将2种检查方法的结果对比病理学结果。结果 64例患者经病理检查共有39例确定为胎盘植入,合并前置胎盘35例(29例中央性前置胎盘、3例部分性前置胎盘、3例边缘性前置胎盘)。64例患者经超声检查共有37例为胎盘植入,有3例被排除;经磁共振检查共有33例为胎盘植入,有2例被排除。两种检查方法的灵敏度、特异度及诊断符合率相比,差异无统计学意义(P>0.05)。结论 胎盘植入经超声与MRI诊断均有较高敏感度、准确性与特异度,但在行子宫后壁胎盘植入诊断上,MRI效果更佳,因此可将MRI用于超声补充检查,可提高胎盘植入诊断准确率,降低漏诊可能。Objective To explore and compare the value of ultrasound and magnetic resonance imaging(MRI)in the diagnosis of placenta accreta in second trimester pregnancy.Methods The clinical data of 64 cases of second trimester pregnancy with suspected placenta accreta in Guangdong Women and Children Hospital from February 2018 to February 2020 were collected.All patients were examined by color Doppler ultrasound and magnetic resonance imaging(MRI).The results of the two methods were compared with the pathological results.Results Among 64 patients,39 cases were confirmed as placenta accreta by pathological examination,35 cases were complicated with placenta previa(29 cases of central placenta previa,3 cases of partial placenta previa,3 cases of marginal placenta previa).There were 37 cases of placenta accreta by ultrasound examination and 3 cases were excluded;there were 33 cases of placenta accreta by MRI examination and 2 cases were excluded.The sensitivity,specificity and diagnostic coincidence rate of the two methods were compared(P> 0.05).Conclusion Both ultrasound and MRI have high sensitivity,accuracy and specificity in the diagnosis of placenta accreta,but MRI has better effect in the diagnosis of placenta accreta in the posterior wall of uterus.Therefore,MRI can be used in the supplementary examination of ultrasound to improve the diagnostic accuracy of placenta accreta and reduce the possibility of missed diagnosis.
