研究目的:

应用磁共振检查构建三维阴道分娩模型,预测阴道分娩成功率,并且比较该模型与既往的骨盆径线测量预测阴道分娩模型预测阴道分娩的准确性。  

Objectives of Study:

To develop a three-dimension model in which pelvis and fetal head are reconstructeda to determine whether the fetal head could pass through the bony birth canal. To compare the predictive value of our model with previous pelvimetry model.
