摘要
目的 用CHN图谱法评估儿童青少年左右手骨龄发育是否一致,为临床应用提供依据.方法 从医院PACS系统中筛选2008年至2012年间因急诊外伤摄手腕部平片者,共选取1.0～19.0岁患者1380例,其中双手摄片者19例（男3例,女16例）,余1361例中左手摄片605例、右手摄片756例,其中男656例、女706例.由2名有经验的放射科医师,对照CHN骨龄图谱,盲法评估骨龄.首先随机抽取60例,评价2名观察者的一致性;后将左右手骨龄与相应实际年龄的差值进行独立样本t检验,并建立回归模型分析其差异.结果 用CHN图谱法评测骨龄,观察者间与同一观察者内差异无统计学意义（P值均＞0.05）.19例双手摄片患者左右手骨龄完全相同;不同个体男性在16.0 ～16.9、17.0 ～ 17.9岁年龄段,女性在6.0～6.9岁年龄段,所有样本在6.0 ～6.9、16.0～16.9岁年龄段左右手骨龄与实际年龄差值有统计学意义.回归模型分析显示,控制入组人员左右手实际年龄差异的情况下,左右手骨龄差异无统计学意义（t=-0.427,P=0.670）.结论 用CHN图谱法评测的骨龄,左右手差异无统计学意义,在临床应用时可根据实际情况选用,不必拘泥于左手.
Objective To study the average difference of CHN atlas method bone age （BA） determination （left-vs.right-hand） for children and adolescents.Methods Radiographs of hands of healthy children and adolescent （age range：1.0-19.0 years） were analysed to determine BA,producing analysis results for 1380 hand images.The images were assessed by two radiologists based on CHN atlas method,who were blinded to the chronological age （CA） of them.The intra-and inter-observer variations were used for evaluating the reliability of CHN atlas method.The difference of BA using left-or right-hand BA was evaluated by t test.Results No significant difference was found for intra-or inter-observer variations （P 〉 0.05）.The BAs of left-and right-hand radiograph showed significant difference in the groups for boys （16.0-16.9,17.0-17.9 years）,girls （6.0-6.9 years） and both of them （6.0-6.9,16.0-16.9 years）.The regression model analysis showed no significant difference（t =-0.427,P =0.670）.Conclusion Comparison of left-and right-hand BA shos no significant difference using CHN atlas method,indicating that either hand could be used to determine BA.
