Concordance Between MR Safety Guidance Documents on Conditions for a Safe MR Environment

Area of Science:

• Medical Imaging Physics
• Radiological Safety
• Healthcare Facility Design

Background:

• Safe Magnetic Resonance (MR) practice relies on environmental conditions established during facility design, construction, and equipment procurement.
• Institutional MR safety programs must integrate MR environment conditions and tailored staff training.

Purpose of the Study:

• To assess the concordance of conditions for a safe MR environment across prominent national guidance documents.
• To identify commonalities and discrepancies in MR safety recommendations.

Main Methods:

• Analysis of six national MR safety guidance documents from countries with high MR system density.
• Extraction and categorization of recommendations related to facility design, MR equipment, and peripheral equipment.
• Descriptive statistical analysis to quantify concordance.

Main Results:

• High concordance observed in facility design (21/25 conditions) and peripheral equipment (10/13 conditions).
• Moderate concordance found for MR equipment features (7/9 conditions).
• Identified common and divergent recommendations across analyzed national guidelines.

Conclusions:

• This comparative analysis highlights shared and differing recommendations for MR facilities and equipment.
• Findings can assist in identifying weaknesses in existing MR environments and inform the development of new safety guidance and training materials.
• The study provides a basis for improving MR safety standards globally.
