摘　　要：目的 建立利用胸部正位CR片影像学变化判定年龄的方程,并评价其法医学意义。方法 收集381例汉族成年人胸部正位CR片样本,其中男性208例,女性173例。选取胸部右侧第一肋胸骨端、左侧第一肋胸骨端、右侧第五肋胸骨端、左侧锁骨骨小梁和左侧锁骨松质骨网眼5项特征性指标,对351例样本进行描述评分,运用SPSS 19.0软件进行多元线性回归模型条件的基本论证,建立回归方程。并使用30例样本对方程的准确性进行盲测。结果 本文所选取的5项胸部正位CR片特征性指标与年龄的关系可以使用线性回归模型（P〈0.05）;建立了1组全指标回归方程和2组分组逐步回归方程,全指标回归方程估计值的标准误男性和女性分别为2.83岁和3.41岁,低年龄组（18-35岁）男性和女性分别为2.47岁和2.79岁,高年龄组（36-50岁）男性和女性分别为2.39岁和2.55岁;随机选取30例样本的盲测结果,误差在3岁以内的,全指标回归方程男性和女性分别为80.0%和73.3%,分组回归方程男性和女性分别为86.7%和80.0%。结论 利用胸部正位CR片影像学特征变化可判定年龄。Objective To establish the equation of chest CR for the estimation of age, and evaluate the significance of forensic medicine. Methods 5 measurements were selected to carry on the independent samples, and the status were analyzed by SPSS 19.0. Results The 5 measurements and age were line-related（P〈0.05）; Three group regression models were formulated; In a separate test, a control sample of 30 chest CR that not involved with formulating the regression equation was correctly estimated with 73.3% to 86.7% accuracy within 3 years. Conclusion The method set up in this paper can be used to estimate the age of Chinese Han adults.
