It is expected that AI medical devices would be introduced in medical images earlier than in other fields, and in fact, there are many cases where AI-based bone age medical devices are used in primary medical institutions. Besides, there are few studies comparing bone age and final adult height prediction of humans and AI. [1][2][3] Medical image reading by AI is by deep learning based on the GP and TW methods, and this study aimed to compare the accuracy of bone age and final adult height prediction of VUNO Med®-BoneAge™, the most commonly used AI program in Korea and specialist.Our study included 190 children and adolescents (73 male and 117 female) aged 8-12 years who visited the Growth Clinic of Pediatric Endocrinology in 2012 to evaluate their bone age (BA) and predicted adult height (PAH). The height, weight, BMI, and height of the father and mother were retrospectively reviewed, and their BA and PAH were predicted based on the GP method by pediatric endocrinologist and musculoskeletal specialist of radiology in 2012 and parents' and subject's height in 2021 were collected by a telephone survey. [4][5] Those who had chronic diseases, treatment to improve growth, height below 3 percentile or above 97 percentile in 2012, the difference in chronological age and BA is above 2 years, did not reach final adult height(FAH) by 2021 were excluded. Of the total 961 individuals (322 male and 639 female), 190 (73 male and 117 female) were studied.In this study, VUNO Med®-BoneAge™ was used as an AI medical device, and its principle was based on deep learning to find the atlas of the most statistically similar bone age and to provide the final value to the first decimal place through the matching rate
