磁共振成像在胎儿检查中的应用价值

目的 探讨磁共振成像在胎儿检查中的应用价值。方法回顾性分析B超发现胎儿发育异常并经引产或手术证实的8例孕妇胎儿MR图像，并将MR与B超的图像进行对比分析。结果 胎儿发育异常的病种有：前置胎盘2例，胎儿肾脏发育不良1例，先天性膈疝1例，羊水过少2例，腹膜后畸胎瘤1例，小脑发育不良1例。与B超相比，MRI可清晰显示B超发现的胎儿异常。结论磁共振成像在胎儿检查中具有重要的临床应用价值，当B超怀疑胎儿发育异常时MRI更是重要的补充。

The role of magnetic resonance imaging in fetus examination

Objective To explore the value of magnetic resonance imaging (MRI) in fetus examination. Methods The MR images of 8 women with complicated pregnancies discovered by ultrasonography were analyzed retrospectively and compared with ultrasonography. Results Fetus heteroplasia included placenta previa (n=2), congenital diaphragmatic hernia. (n=1), agenesis of kidney (n=1), lack of amniotic fluid (n=2), retroperitoneal teratoma (n=1) and agenesis of cerebellum (n=1). MRI could clearly display abnormities of fetus that suspected by ultrasound. Conclusion Magnetic resonance imaging plays a significant role in fetus examination and has become an adjuvant method when the fetus heteroplasia were suspected by ultrasonography.
