摘要
目的通过头颅CT片研究性别识别的方法。方法在头颅CT片测量头颅多项指标,应用各个指标进行二分类logistic回归分析建立性别判定方程。结果应用颧弓间距指标可以建立一元方程:Z=-69.051+0.521X1,P=1/1+e-Z。应用多项指标可以建立多元方程:Z=-115.873+0.585X1+0.119X4+0.254X7+0.229X8+0.101X6,P=1/1+e-Z。结论根据头颅CT片进行性别判定时,最好是测量多项指标。在指标不全时,就只需测量颧弓间距,也可以有较好的判别效果。
Objective To explore the methods for sex determination on head CT film. Methods To establish the sex determination equations by binary regression analysis of cranial skeletal indices obtained on head CT film. Results A single element equation by applying the index of the width of ansa capitis and a multi-element equation by applying multitude indices were established. Conclusion The equations for sex determination on head CT film were established.
