Abstract: 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.
