This study assessed the sex-discrimination potential of the sternum in a Japanese population using three-dimensional (3D) computed tomographic (CT) images. A total of 200 cadavers (100 males, 100 females) who underwent postmortem CT and subsequent forensic autopsy between December 2011 and June 2014 were used. Five measurements of each sternum were performed on 3D CT reconstructed images that extracted only bone data, and two sternal dimensions and three indices were calculated. Univariate discriminant function analyses using these linear measurements and calculated sternal dimensions and indices yielded sex classification accuracy rates of 62.5-84.0%, and 63.0-90.5%, respectively. The results of this study indicate that sternal measurements may be useful for the forensic assessment of sex in Japanese individuals, particularly in cases where better predictors, such as the pelvis or skull, are unavailable.
本研究使用三维（3D）计算机断层扫描（CT）图像评估了日本人群中胸骨的性别歧视潜力。研究共使用了200具尸体（100例男性，100例女性），这些尸体于2011年12月至2014年6月期间接受了死后CT检查及随后的法医尸检。在仅提取骨骼数据的3D CT重建图像上对每具胸骨进行了五项测量，并计算了两个胸骨尺寸和三个指数。使用这些线性测量值以及计算出的胸骨尺寸和指数进行单变量判别函数分析，性别分类准确率分别为62.5 - 84.0%和63.0 - 90.5%。本研究结果表明，胸骨测量可能有助于对日本人进行法医性别评估，特别是在无法获得更好的预测指标（如骨盆或颅骨）的情况下。
