摘　　要：目的探讨胎儿尸体MR检查替代胎儿尸体检查的可行性。方法对产前超声诊断胎儿畸形、并终止妊娠后的33胎行MR检查,与尸体解剖对照,分析比较产前超声结果、胎儿尸体MRI与尸体检查结果。结果 33胎中尸体检查共检出胎儿畸形42处。产前超声诊断符合率88.10%(37/42),胎儿尸体MRI诊断符合率92.86%(39/42)。4胎心脏异常中,仅有2胎MRI结果与尸体检查符合。除外心脏结构畸形,胎儿尸体MR检查与尸体检查结果符合率为97.37%(37/38)。结论在患者家属拒绝胎儿尸体检查时,胎儿尸体MR检查有望成为一个较好的、可被家属接受的替代选择。Objective To explore the feasibility of postmortem fetus MRI instead of autopsy.Methods Third-three fetuses with fetal malformation detected by prenatal ultrasound underwent postmortem fetus MRI and autopsy after termination of pregnancy.The results of prenatal ultrasound,postmortem fetus MRI and autopsy were compared.Results All of 42 malformations were detected in 33 fetuses by autopsy.The coincidence rate of prenatal ultrasound and postmortem fetus MRI was 88.10%（37/42）and 92.86%（39/42））,respectively.In 4fetuses with cardiac malformations,only 2fetuses were detected correctly by postmortem fetus MRI.Except the cardiac structural abnormalities,the coincidence rate was97.37%（37/38）for postmortem fetus MRI and autopsy.Conclusion Postmortem fetus MRI could be an alternative accepted method for conventional autopsy when conventional autopsy is refused by parents.
