经腹超声和MRI对胎盘植入的诊断分析 [中文引用][英文引用]

目的 分析经腹超声和MRI对不同类型胎盘植入的植入诊断价值。方法 回顾本科孕晚期均行经腹多普勒超声和MRI检查，并手术确定胎盘植入的42例病例，术中对42例胎盘植入进行分型，胎盘粘连10例，胎盘植入21例，穿透性植入11例，分析对比两种检查方法对不同类型胎盘植入的植入诊断准确性。结果：胎盘粘连中MRI诊断植入正确率80%（8/10）、超声20%（2/10）；胎盘植入中MRI植入诊断正确率90%（19/21）、超声52%（11/21）；穿透性植入中MRI诊断植入正确率90%（10/11）、超声90%（10/11）。结论 不同类型胎盘植入中胎盘粘连和胎盘植入MRI诊断胎盘植入明显优于经腹多普勒超声，但穿透性胎盘植入两者诊断无显著性差别。

Objective To analyze the effect of transabdominal ultrasound and MRI in diagnosis of the various types of morbidly adherent placenta. Method Retrospectively analyzing samples cases of performed transabdominal ultrasound and MRI in late pregnancy and surgically confirmed the morbidly adherent placenta in 42 cases, and are typed based on result; 10 cases of placenta accrete, 21 cases of placenta increta, 11 cases of placenta percreta. The two methods of transabdominal  ultrasound and MRI had been compared on the diagnostic accuracy of the various types of morbidly adherent placenta. Results The accuracy of MRI diagnosis of placenta accrete is 80%（8/10）, transabdominal ultrasound 20%（2/10）；The accuracy of MRI diagnosis of placenta increta  is 90%(19/21), transabdominal ultrasound 52%(11/21); The accuracy of MRI diagnosis of placenta percreta is 90%(10/11), transabdominal ultrasound 90% （10/11）. Conclusions The diagnose accuracy of MRI exceed transabdominal ultrasound significantly in the cases of placenta accrete and placenta increta, but no significant difference between the diagnose accuracy in the case of placenta percreta.
