摘　　要：目的为给围产期孕妇腹、盆部B超、MR诊断提供矢状断面解剖学基础。方法将1例足月妊娠尸体做腹盆部MR扫描,获取图像数据。用电动带锯按等距法制成与正中矢状面平行的腹、盆部连续矢状断层标本,并获取连续矢状断层标本图像数据。结果足月孕妇腹盆部矢状断面的解剖结构在标本和MR图像上均得到了很好地显示;胎盘和宫内胎儿主要脏器显示层面与母体椎骨之间的有较为固定的对应关系。结论足月孕妇连续矢状断层标本、MR图像分析结果能够为围产期孕妇腹、盆部B超、MR诊断提供正常的形态学资料。Objective To provide sagittal sectional anatomic data for guidance in B- ultrasound and MR/diagnosis in abdominal and pelvic parts of pregnant women in the third trimester. Method After MRI scanning in abdominal and pelvic part of a pregnant woman cadaver in third trimester, the abdominal and pelvic parts was sectioned into serial sagittal 10-millimeter thick sections with equal intervals using a dynamoelectric beltsaw. Result The anatomic structures in sagittal sectional imaging and MR/in abdominal and pelvic parts of the cadaver with full term pregnance were well displayed, and the spatial relationship of the location of the placenta and fetal main organs to the materal vertebrae in sagittal sections of the specimen and the MR images was relatively constant. Conclusion The analytic results of the MR and serial sagittal sectional images of the cadaver can provide normal and useful anatomic guidance for B- ultrasound and MR/diagnosis in abdominal and pelvic parts of the pregnant women in the third trimester.
