Magnetic resonance safety

Area of Science:

• Medical Physics
• Radiological Safety
• Biomedical Engineering

Background:

• Safe operation of clinical and pre-clinical Magnetic Resonance (MR) systems is paramount.
• A diverse range of potential hazards are associated with MR environments.
• Understanding these risks is essential for preventing adverse events.

Purpose of the Study:

• To provide a comprehensive overview of Magnetic Resonance (MR) safety.
• To cover both the theoretical underpinnings and practical guidance for MR safety.
• To consolidate information on national, international, and local MR safety policies.

Main Methods:

• Review of theoretical background on MR safety issues.
• Discussion of practical guidance and safety policies for MR installations.
• Analysis of information from national and international MR safety guidance sources.

Main Results:

• Consideration of projectile effects and hazards from static and time-varying magnetic fields.
• Examination of issues including peripheral nerve stimulation, tissue heating, and RF burns.
• Discussion of contrast agents, auditory effects, medical implants, and biological safety.

Conclusions:

• Effective MR safety management requires understanding theoretical hazards and practical guidance.
• Adherence to national, international, and local safety policies is mandatory for all MR installations.
• Comprehensive safety protocols must address magnetic field interactions, device compatibility, and biological effects.
