Course Description
Magnetic resonance imaging (MRI) is generally considered to be a safe imaging modality because it does not involve ionizing radiation. However, there are still significant safety risks associated with MRI scans. These risks include potential projectile events due to the strong static magnet as well as tissue heating and acoustic injury from the pulsed radiofrequency and gradient magnetic fields. To minimize these risks, it is important to implement strong safety protocols and provide appropriate education for patients and staff. A valuable resource for MRI safety is the American College of Radiology's (ACR's) Manual on MR Safety. The Manual was recently updated to cover timely topics such as ultra-low- and ultra-high-field systems, point-of-care and interoperative systems, remote scanning practices, and a revised limit for the MRI fringe field. The updated Manual also includes new guidance on improving MR policies and training materials. This course will review the latest updates to the ACR's Manual on MR Safety and provide a comprehensive overview of important safety topics highlighted in the guidelines. Specifically, key topics include MRI safety zones, proper labeling of devices, and the roles of MR personnel. It will also examine the safety risks of cryogen and the 3 electromagnetic fields used during MRI scanning. Patient safety considerations will be addressed, including screening methods, risk assessments of medical devices, and clear communication. Finally, unique safety considerations for special patient populations and alternative MRI environments will be covered.

Learning Objectives
After reviewing the content, participants should be able to:

• SUMMARIZE key updates to the American College of Radiology's ACR Manual on MR Safety.
• IDENTIFY the essential components of a magnetic resonance imaging (MRI) system that contribute to a safe environment, including the demarcation of safety zones, equipment labeling, and the responsibilities of MRI RTs.
• EXPLAIN the potential risks associated with MRI equipment, including risks from cryogen use and electromagnetic fields.
• PRACTICE effective pre-examination, in-scan, and postexamination safety procedures, including patient screening and monitoring, to ensure safety during MRI imaging studies.
• OUTLINE the unique safety considerations for special patient populations, such as pediatric and pregnant patients, and alternative MRI environments, including ultra-low and high-field MRI systems.
