Preserving the value of legacy film-based teaching files in pediatric radiology.

Senior pediatric radiologists who have spent a major portion of their careers interpreting conventional film-screen radiographic studies have collected a wealth of hard-copy teaching material that is at risk of becoming obsolete. The teaching value and usefulness of analog film teaching files can be preserved using available hardware and standard software. The final product can be made available in a high-quality digital format to students, trainees and faculty without complicated search-and-retrieval methodology.

Osteochondritis Dissecans of the Elbow in Children: MRI Findings of Instability.

The purpose of this study was to investigate the performance of MRI criteria for predicting instability of osteochondritis dissecans (OCD) lesions of the elbow in children. This retrospective study included 41 children with 43 OCD lesions of the elbow who underwent an MRI examination between April 1, 2010, and May 31, 2018. Two radiologists blinded to clinical outcomes reviewed MRI studies to determine the presence or absence of joint effusion, osteochondral defect, intraarticular body, overlying cartilage changes, subchondral bone disruption, rim of high signal intensity on T2-weighted images, cysts, marginal sclerosis, and perilesional bone marrow edema.
