Management of metallic implants in radiotherapy: 2025 update

Abstract

The number of patients receiving radiotherapy while having metallic implants is steadily increasing. These implants degrade the quality of computed tomography images used throughout the radiotherapy process, including delineation, dosimetry, and dose delivery. This document presents the updated recommendations from the Société française de radiothérapie oncologique (SFRO; i.e., the French society for radiation oncology), outlining the advantages and limitations of various existing and emerging methods designed to reduce the impact of metallic implants on radiotherapy quality and safety.
