摘　　要：目的:利用寰椎形态学指标建立吉林地区男女性别的鉴定方法并评价其鉴定效果。方法:分别应用男女头颈部CT影像资料重建寰椎立体模型,对寰椎8个面的27项指标进行测量,筛选出14个有性别差异的指标。结果:27个线性指标中14项指标的性别差异具有统计学意义(P<0.05),其27项指标的性别鉴定准确率为52.0%～89.3%,其中寰椎全宽准确率达86.7%。对其中9项性别鉴定具有统计学意义的指标使用逐步判别分析法,得到1个性别鉴定准确率达到95.8%的方程:Y=1.308W-0.409CDF-0.469LTPSD-0.849LUACD+0.478RUACD+0.332RDACD+0.363ATH-0.334PTH-0.236PAL。结论:寰椎形态可作为吉林地区男女性别鉴定的重要依据之一。Objective To establish the method of using the atlas morphological indexes for sex determination in Jilin province and to evaluate its effect.Methods The clinic neck CT images were used to reconstruct the 3D image of atlas.A total of 27 linear measurements on 8 aspects of the atlas were measured and the ratios were calculated.The 14 items were selected.Results Of the total 27 linear measurements,14 were sexually dimorphic（P0.05）,and the accuracies of sex determination of 27 indexes were 52.0%-89.3%.The highest accuracy was width of vertebral body（86.7%）.A function with variables predicting sex with 95.8% accuracy was derived by using stepwise method of discriminant function analysis：Y=1.308W-0.409CDF-0.469LTPSD-0.849LUACD＋0.478RUACD＋0.332RDACD＋0.363ATH-0.334PTH-0.236PAL.Conclusion The method of using atlas traits for sex determination in Jilin province is practicable.
