Age estimation is routinely undertaken by comparing radiographs of the individual in question to published reference samples of individuals of known age. This study examines the reliability of age estimation utilizing the Greulich and Pyle atlas in relation to both left- and right-hand/wrist radiographs and explores whether reversing right-hand/wrist radiographs, so that they are in the same anatomical orientation as those images used in the atlas affects reliability. A total of 403 left-hand/wrist radiographs and 415 right-hand/wrist radiographs were age assessed using the Greulich and Pyle atlas. Analysis showed that there is no significant loss in reliability when radiographs of the right hand (women R(2) = 0.887 and men R(2) = 0.907) are utilized instead of the left (women R(2) = 0.939 and men R(2) = 0.940) or when they are assessed as mirror images to those printed in the reference atlas (reversed female left hand R(2) = 0.929 and reversed male left hand R(2) = 0.931).
年龄估计通常是通过将相关个体的X光片与已发表的已知年龄个体的参考样本进行比较来进行的。本研究考察了使用格吕利希和派尔图谱对左手和右手/腕部X光片进行年龄估计的可靠性，并探讨将右手/腕部X光片翻转，使其与图谱中使用的图像处于相同解剖学方向，是否会影响可靠性。使用格吕利希和派尔图谱对总共403张左手/腕部X光片和415张右手/腕部X光片进行了年龄评估。分析表明，使用右手X光片（女性R² = 0.887，男性R² = 0.907）而非左手X光片（女性R² = 0.939，男性R² = 0.940），或者将其作为参考图谱中印刷图像的镜像进行评估时（翻转的女性左手R² = 0.929，翻转的男性左手R² = 0.931），可靠性没有显著损失。
