摘　　要：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 confirmed 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.
