MRI Safety of Active Implanted Devices: Past, Present, Future
Description
The increasing variety and rapid evolution of MR-conditional, active implanted medical devices (AIMDs) in the last decade has expanded the medical physicists’ scope of practice to include the provision of expert safety consultation on the presence of these devices in the MRI environment. This role includes the evaluation of potential scanning risks prior to MRI examinations, consultation with radiologists and technologists, and provision of guidance during scans for management of safety while maintaining image quality. The associated increase in scanning complexity has helped inspire new CPT® codes introduced in 2025 for billing of medical physicist services in support of these activities. This session will provide a comprehensive review of the current and developing state of practice for the provision of MR safety guidance of AIMDs. It will cover the unique complexities associated with the management of MRI safety for various devices, including neurostimulators, cardiac devices and cochlear implants. Additionally, the session will provide insights into the emerging area of scanning pediatric patients with AIMDs, as labels applied to adult devices may not always be applicable to pediatric patients. The session aims to equip medical physicists with the knowledge to support MR safety of patients with AIMDs. By attending this session, attendees will gain insight into the latest developments, future directions and overall evolution of AIMD MRI safety.
