摘要： 目的 通过计算机体层成像（computerized tomography，CT）技术测量第2胸椎与第3腰椎的形态学 相关数据，分析其性别差异并建立性别判别分析方程。 方法 采集华中地区成年人影像资料样本274例 （实验组203例，验证组69例），分别对第2胸椎与第3腰椎的4个线性数据（椎体横向最大长度、纵向最大长 度、椎孔横向最大长度、椎孔纵向最大长度）、1个角度数据（棘突间夹角）、2个面积数据（椎孔面积、椎体横 断面总面积）进行测量，得出3个比值［椎体横向最大长度/纵向最大长度、椎孔横向最大长度/纵向最大长 度、椎孔面积（/ 椎体横断面总面积-椎孔面积）］及1个角度（棘突间夹角），建立判别方程进行性别判别分 析。 结果 第2胸椎与第3腰椎形态与性别存在相关性，建立了4个单指标判别公式及11个多指标判别公 式。验证组代入公式检验，得到单指标判别方程的最大判别准确率为75%，多指标判别方程的最大判别准 确率为83%。 结论 利用第2胸椎与第3腰椎的形态学指标进行个体性别分析具有一定可行性。

Abstract: Objective The morphological data of the second thoracic vertebra and the third lumbar vertebra were measured by computerized tomography （CT）. The sex differences were analyzed and the discrimination equation was obtained. Methods The data of 274 adults （203 cases from experimental group and 69 cases from validation group） from central China were collected. Four linear data （maximum transverse length of vertebral body, maximum longitudinal length of vertebral body, maximum transverse length of vertebral foramen, maximum longitudinal length of vertebral foramen）, one angle data （angle between spinous processes） and two area（vertebral foramen area, total cross-sectional area of vertebral body） data of the second thoracic vertebra and the third lumbar vertebra were collected, respectively. Then three ratios［maximum transverse length/ maximum longitudinal length of vertebral body, maximum transverse length/ maximum longitudinal length of vertebral foramen, vertebral foramen area/ （total cross-sectional area of vertebral body-vertebral foramen area）］ and one angle （angle between spinous processes） were obtained. The discriminant equation was established for sexual discriminant analysis. Results The morphology of the second thoracic vertebra and the third lumbar vertebra was related with gender. Four single index discriminant formulae and eleven multi- index discriminant formulae were established. The 69 validation group samples were substituted into the formula for testing, and the maximum discriminant accuracy rate of the single-index discriminant formula was 75%. The maximum discriminant accuracy rate of multi-index discriminant formula was 83%. Conclusion It is feasible to conduct individual sex analysis by the morphological indexes of second thoracic vertebra and the third lumbar vertebra. The indexes have important application values in practice.
