Motivation: The standard procedure established in many countries for the forensic age estimation of living persons is based on radiological examinations with ionizing radiation, which are, however, controversial as there is no medical indication for their use. Goal(s): The goal was to evaluate MRI as an alternative radiation-free method for age estimation. Approach: MR examinations of the hand, clavicles, and third molars were performed in 338 subjects. The developmental stage of the regions was assessed using established staging systems, and a latent trait model was used to combine the stages. Results: The results clearly demonstrated the applicability of MRI in a multifactorial model approach. Impact: The MR examination of the hand, clavicles, and third molars represents a radiation-free alternative for forensic age estimation in living adolescents. The approach yielded good results when applied in a combined statistical model.
