OBJECTIVE
The aim of this study is to describe MR imaging appearances of the fetal lumbar spine in vivo at different gestational ages (GAs).
METHODS
This retrospective study was approved by the Third Affiliated Hospital of Zhengzhou University. We collected MR images and clinical data of 93 fetuses in our hospital. All the MR images were obtained by 3-T MR. All had the mid-sagittal plane of steady state free precession sequence (Trufi) of the lumbar spine, which could show the lumbar vertebra and conus medullaris (CM). Regression analysis was made between GA and heights of lumbar vertebral body ossification center (LVBOC), lengths of LVBOC, and heights of intervertebral gap (IVG).
RESULTS
There were good linear correlations between the heights of LVBOC and GA (P < 0.001), lengths of LVBOC and GA (P < 0.001), and heights of IVG and GA (P < 0.001).
CONCLUSION
We showed the different development of each LVBOC and IVG which caused the difference of the shape of LVBOC and IVG.
目的
本研究旨在描述不同胎龄（GA）胎儿腰椎的活体磁共振成像（MR）表现。
方法
本回顾性研究经郑州大学第三附属医院批准。我们收集了我院 93 例胎儿的 MR 图像和临床资料。所有的 MR 图像均由 3-T MR 获得。所有图像均显示了腰椎的稳态自由进动序列（Trufi）的正中矢状面，可显示腰椎和脊髓圆锥（CM）。对 GA 与腰椎椎体骨化中心（LVBOC）高度、LVBOC 长度和椎间间隙（IVG）高度进行回归分析。
结果
LVBOC 高度与 GA 之间存在良好的线性相关性（P<0.001），LVBOC 长度与 GA 之间存在良好的线性相关性（P<0.001），IVG 高度与 GA 之间存在良好的线性相关性（P<0.001）。
结论
我们展示了每个 LVBOC 和 IVG 的不同发育情况，这导致了 LVBOC 和 IVG 形状的差异。
