Comparative analysis of an automated bone age tool with manual assessment in a multiethnic Southeast Asian paediatric cohort in Singapore.

Background: Bone age assessment is essential for evaluating growth and pubertal disorders, but manual methods such as the Greulich-Pyle atlas are subject to inter-observer variability. Automated tools like BoneXpert may improve accuracy and consistency.

Objective: To validate the accuracy and reliability of BoneXpert, an automated bone age assessment tool, compared to traditional manual methods performed by paediatric endocrinologists and radiologists in a multiethnic paediatric cohort in Singapore.
