目的：探讨前置胎盘合并胎盘植入的产前MRI诊断价值。材料与方法回顾性分析经手术病理证实的48例前置胎盘患者的临床及MRI资料，包括前置胎盘合并胎盘植入者12例，总结分析其MRI影像学特征。结果 MRI术前诊断前置胎盘43例，其中完全性前置胎盘31例，部分型前置胎盘9例，边缘型前置胎盘3例，总体诊断符合率为89.5%(43/48)。MRI术前正确诊断胎盘植入9例，诊断符合率为75.0%(9/12)。结论 MRI对前置胎盘及胎盘植入有较高的诊断价值，综合MR不同成像序列可提高术前诊断准确率。

Objective: To investigate the prenatal MRI imaging features of placenta previa complicated with placenta accreta.Materials and Methods:The clinical and MRI data of 48 cases of placenta previa including 12 placenta accreta conifrmed by clinic and surgery were retrospectively analyzed.Results: Forty-three cases of placenta previa were diagnosed by MRI pre-operation, including 31 cases of complete placenta previa, 9 cases of partial placenta previa and 3 cases of marginal placenta previa. The overall diagnose accordance rate was 89.5% (43/48). Nine cases of placenta accreta were diagnosed by MRI pre-operation, the diagnose accordance rate was 75.0% (9/12).Conclusions:MRI has a high accuracy for the diagnosis of placenta previa, the combination of different MR sequence can make accurate diagnosis possible.
