Using a Siemens-Biograph 128 mCT camera the morphometric analysis of the L4 vertebral body and its ossification center were done in 55human fetuses aged 17 to 30weeks. No sex differences were found. The mean height, transverse and sagittal diameters of L4 vertebral body followed the logarithmic functions: y = -11.797+ 5.208 × ln(age) ± 0.372, y = -23.462 + 9.428 × ln(age) ± 0.702, y = 2.770 + 13.521 × ln(age) ± 1.722, respectively. The mean cross-sectional area of L4 vertebral body followed the linear function: y = -30.683 + 1.976 × age ± 2.701. The mean volume of L4 vertebral body followed the second-degree polynomial function: y = -93.983+ 0.385 × (age)² ± 23.707. The mean transverse and sagittal diameters of the ossification center of L4 vertebral body followed the natural logarithmic function: y = -27.106 + 10.178 × ln(age) ± 0.769 and y = -13.345 + 5.458 × ln(age) ± 0.424, respectively. The mean cross-sectional area and the volume of the ossification center of L4 vertebral body followed the linear function: y = -30.683 + 1.976 × age ± 2.701 and y = -43.214 + 2.760 × age ± 4.085, respectively.
使用西门子Biograph 128 mCT相机，对55例17至30周龄的人类胎儿的L4椎体及其骨化中心进行了形态计量学分析。未发现性别差异。L4椎体的平均高度、横径和矢状径分别遵循对数函数：y = -11.797 + 5.208 × ln(年龄) ± 0.372，y = -23.462 + 9.428 × ln(年龄) ± 0.702，y = 2.770 + 13.521 × ln(年龄) ± 1.722。L4椎体的平均横截面积遵循线性函数：y = -30.683 + 1.976 × 年龄 ± 2.701。L4椎体的平均体积遵循二次多项式函数：y = -93.983 + 0.385 × (年龄)² ± 23.707。L4椎体骨化中心的平均横径和矢状径分别遵循自然对数函数：y = -27.106 + 10.178 × ln(年龄) ± 0.769和y = -13.345 + 5.458 × ln(年龄) ± 0.424。L4椎体骨化中心的平均横截面积和体积分别遵循线性函数：y = -30.683 + 1.976 × 年龄 ± 2.701和y = -43.214 + 2.760 × 年龄 ± 4.085。
