Magnetic resonance imaging (MRI) for forensic age estimation is among the research issues since it does not lead to radiation exposure. In this study, the ossification stage of the proximal humeral epiphysis was determined retrospectively in 178 male and 109 female individuals in the 12 to 30-year age group using 3.0 T MRI. All images were evaluated with the proton density fat saturated turbo spin echo (PD TSE FS) sequence and the T2 TSE FS sequence. A five-stage scoring system was used following the method of Dedouit et al. The relevant statistics were defined as minimum, maximum, mean ± standard deviation, 95% confidence interval of mean and median and the intra- and interobserver agreement levels were very good (κ > 0.80). There were no significant age differences between males and females in any of the stages (all p-values>0.05). According to the present study, stage 5 was initially observed at age 22 years for both genders. According to our results, it is possible to determine the completion of the 18th year of life in either gender on the shoulder joint. Proximal humeral epiphysis ossification may be used as an additional method for forensic age estimation through MRI.
磁共振成像（MRI）在法医年龄估计中的应用是研究的问题之一，因为它不会导致辐射暴露。在这项研究中，使用 3.0T MRI 对 178 名男性和 109 名女性 12 至 30 岁年龄组的肱骨近端骨骺骨化阶段进行了回顾性评估。所有图像均使用质子密度脂肪饱和涡轮自旋回波（PD TSE FS）序列和 T2 TSE FS 序列进行评估。采用 Dedouit 等的方法，采用五阶段评分系统。相关统计数据定义为最小值、最大值、平均值±标准差、平均值的 95%置信区间和中位数以及观察者内和观察者间的一致性水平非常好（κ>0.80）。在任何阶段，男性和女性之间的年龄差异均无统计学意义（所有 p 值均>0.05）。根据本研究，男女两性的第 5 阶段最初在 22 岁时观察到。根据我们的结果，可以在肩关节确定任何性别的第 18 年的生活结束。通过 MRI 对肱骨近端骨骺的骨化可以作为法医年龄估计的附加方法。
