摘　　要：目的:探讨MRI对前置胎盘的诊断价值。方法:应用3.0TMRI对9例临床怀疑前置胎盘的患者进行盆腔MRI扫描,分析MRI影像诊断征象,并与手术结果进行对照。结果:9例患者均经手术确诊为前置胎盘:完全性前置胎盘共6例,边缘性前置胎盘1例,部分性前置胎盘2例;前置胎盘合并瘢痕子宫4例,前置胎盘合并胎盘植入3例;诊断准确率为100.0%。结论:MRI对前置胎盘诊断准确率较高,能直观显示胎盘位置异常,为临床诊治提供重要依据。Objective： To evaluate the role of MR in the diagnostics of placenta previa. Method： 9 cases of women with placenta previa underwent pelvic MRI scans with 3.0 TMRI.The results of MRI in placenta previa were analyzed and compared with post-operative data. Results： According to the post-operative data,the 9 women were definitive placenta previa cases, including 6 complete placenta previa,1 partial placenta previa,2 marginal placenta previa; 4 placenta praevia combined with scar uterus（there was 1 case of placenta near the uterine scar）,3 placenta praevia combined with placenta accrete; the accuracy was 100.0%. Conclusion： MRI is an accurate imaging modality for diagnosing placenta previa. MRI can intuitively display the abnormal placenta location and provide the basis for clinical diagnosis and treatment.
