Radiography has brought about marked advances in our knowledge of human growth offering information on sequence and timing as well as changes in dimensions and proportions and segmental and "relative" growth. Not only has it been possible to measure growth rates and changes in relative rates at the two ends of a single bone and in homologous bones across the body axis, but it has also been practical to measure rates of bone loss (due to malnutrition and malabsorption) in the presence of simultaneous bone gain. Careful and detailed analysis of the radiographic image, the use of radiogrammetric techniques and extension of the same techniques to the fetal skeleton has afforded new knowledge on continuing growth throughout the life span and on the earliest (fetal) attainment of adult bone shapes and proportions.
放射成像技术在我们对人类生长的认识方面取得了显著进展，它提供了有关生长顺序、时间以及尺寸、比例变化和节段性与“相对”生长的信息。不仅能够测量单根骨头两端以及身体轴线上同源骨头的生长速率和相对速率变化，而且在同时存在骨质增加的情况下测量骨质流失（由于营养不良和吸收不良）速率也切实可行。对放射影像进行细致入微的分析、运用放射测量技术并将这些技术扩展至胎儿骨骼，为我们提供了关于整个生命周期持续生长以及成年骨骼形状和比例最早（胎儿期）达成情况的新知识。
