目的：评价 MRI 对妊娠相关并发症的诊断价值。方法对22例妊娠晚期孕妇、7例产后阴道流血患者、1例孕8周出现不规则阴道流血患者行 MRI 检查。妊娠晚期病例观察胎盘和脐带位置有无异常；孕8周阴道流血患者观察胚胎形态及信号是否正常；产后病例观察有无残留胎盘及其与子宫壁的关系。结果22例妊娠晚期病例中4例胎盘位置正常,18例胎盘前置,8例合并脐带绕颈。剖宫产证实有9例前置胎盘并胎盘植入,其中6例 MRI 提示胎盘植入,另3例 MRI 未报告。7例产后不规则阴道流血患者均见胎盘残留,且合并胎盘植入。孕8周阴道流血患者宫腔见团块状不均匀长 T1长 T2信号,病理证实为葡萄胎。结论MRI 能准确评价前置胎盘、脐带绕颈、胎盘残留及胎盘植入等妊娠相关并发症,并能结合临床对葡萄胎作出诊断。

Objective To discuss the value of MRI in diagnosis of complications related to pregnancy.Methods MRI were per-formed in 22 cases of late pregnancy,7 cases of postpartum with vagina bleeding,and 1 case with eight weeks of gestation following irregular vagina bleeding,respectively.The position of placenta and umbilical cord were observed in the cases of late pregnancy.The shape and signal features of embryo were evaluated in the case of eight weeks gestation following irregular vagina bleeding.Residual placenta and its relationship with the wall of uterus were analyzed in the cases of postpartum with vagina bleeding.Results Among the 22 cases of late pregnancy,normal position of placenta were in 4 cases,placenta previa were in 18 cases,umbilical cord winding around fetal neck in 8 cases.9 cases of placenta previa complicated with placenta accreta were comfirmed by cesarean delivery,how-ever,only 6 cases of placenta accreta were detected on MRI.The residual placenta with placenta accreta was found in all 7 cases of postpartum patients.Hydatidiform mole was proved by pathology in the case of eight weeks gestation following irregular vagina bleeding,and it was showed as a mass with hypointensity on T1 WI and hyperintensity on T2 WI in uterine cavity.Conclusion The complications related to pregnancy such as placenta previa,umbilical cord winding around fetal neck,residual placenta,placenta ac-creta could be correctly displayed on MRI.Hydatidiform mole also could be diagnosed by combining the clinical symptoms with MR images.
