摘　　要：目的 评价超声和MRI检查对胎盘植入的诊断价值。 方法 检索国内外关于胎盘植入的相关文献，提取数据并进行荟萃（Meta）分析，获得超声和MRI的合并敏感度与特异度及受试者工作特征（ROC）曲线的曲线下面积（AUC）。 结果 超声检查的合并敏感度是0.80，合并特异度是0.88，AUC为0.88；MRI检查的合并敏感度是0.86，合并特异度是0.90，AUC为0.93。 结论 超声和MRI对胎盘植入的诊断价值都很高，但MRI是超声的有益补充，其诊断价值略优于超声，2种检查方法的结合更有助于胎盘植入的诊断。Objective To evaluate the diagnostic value of ultrasonography and MRI in the diagnosis of placenta accrete. Methods First, the relevant literatures about placenta aecrete were retrieved at home and abroad, then the data were extracted and Meta-analysis was performed. The combined sensitivity and specificity of ultrasound and MRI and AUC were obtained.Results The combined sensitivity of ultrasonography was 0.80,specificity was 0.88,AUC was 0.88; combined sensitivity of MRI was 0.86,specificity was 0.90,AUC was 0.93.Conclusion Ultrasound and MRI are very valuable in the diagnosis of placenta accrete. However,MRI is a useful complement of ultrasound, and the diagnostic value is slightly better than that of ultrasound. The diagnostic value will be higher when they combined together.
