Epub ahead of print.1432-086Xhttp://hdl.handle.net/10400.21/22879Interventional radiology has rightfully claimed osteoid osteoma (OO) ablation as a success story. Minimally invasive, highly effective, and reproducible, CT-guided thermal ablation has largely replaced surgery as the standard of care. Yet, in pediatric patients, this success is accompanied by a persistent and important concern: the management of ionizing radiation exposure. Despite increasing awareness, radiation dose in pediatric interventional radiology continues to show considerable variability, with limited standardization and few meaningful benchmarks. In this context, the multicenter registry analysis by Wintergerst et al. provides a timely and relevant contribution by systematically evaluating radiation exposure, procedural outcomes, and practice patterns in CT-guided OO ablation.engInterventional radiologyOsteoid osteomaChildrenjournal article10.1007/s00270-026-04454-y
