Accessory equipment considerations with respect to MRI compatibility

Area of Science:

• Medical Imaging
• Biomedical Engineering
• Electromagnetism

Background:

• Third-party accessory equipment is increasingly used with Magnetic Resonance (MR) systems.
• Ensuring the safety and compatibility of these accessories is crucial for patient and staff well-being.
• Regulatory bodies like the Food & Drug Administration (FDA) require clear guidelines for MR accessory use.

Purpose of the Study:

• To address generic issues concerning the compatibility of third-party accessory equipment with MR systems.
• To provide recommendations for the design and testing of MR accessories.
• To ensure the safety performance of accessories within the MR scanning environment.

Main Methods:

• A position paper was issued by the MR Section of the National Electrical Manufacturers Association (NEMA).
• Input was gathered from NEMA member companies manufacturing MR systems and accessories.
• Key safety performance issues were identified and discussed.

Main Results:

• The paper discusses interactions between accessory equipment and MR scanners.
• It addresses potential safety hazards posed by accessory equipment to patients and staff.
• Recommendations cover radiofrequency (RF) coils, patient monitoring, injectors, comfort accessories, and positioning devices.

Conclusions:

• Adherence to NEMA recommendations can enhance the safety and compatibility of third-party MR accessories.
• Consideration of these concepts in product design and testing plans is vital.
• Ensuring MR compatibility protects patients and staff in the MR scan environment.
