The use of MRI poses significant safety considerations for patients and staff and requires those working in MRI to have knowledge and understanding relating to the risks posed by static magnetic fields, time varying electromagnetic fields and biological effects.  

Our publication Safety in Magnetic Resonance Imaging sets out the required knowledge for the radiographic workforce in MRI. It also acts as a practical guidance document for MRI services. 

The recognised guidance and framework for the safe use of MRI in the UK is the Medicines and Healthcare products Regulatory Agency. Safety Guidelines for Magnetic Resonance Imaging Equipment in Clinical Use

MRI Safety Week

Each year in the last week of July MRI safety is highlighted by the MR community. The date reflects the anniversary of the death of a young patient due to an MR unsafe oxygen cylinder being taken into the MR environment.

Each year members of the SoR MR Advisory Group produces materials for MRI services.

These are available to download.

CEMFAW regulations 2016

There are also regulations relating to worker exposure to Electro Magnetic Fields that services and service managers need to be aware of these are known as the CEMFAW regulations which came into effect in the UK in 2016. They are overseen by the Health and Safety Executive in Great Britain and HSENI in Northern Ireland

MR Safety Advice Sheets

A series of MR Safety advice sheets was published by the BIR as part of the 2018 MR Safety Week Activities

The sheets were put together by the BIR MR Special Interest group and consist of the following:

  • Scanning without device manufacturers approval of MRI safety
  • SAR and B1+ RMS
  • Static Magnetic Field
  • Maximum Spatial Gradient
  • Time-varying Magnetic Field Gradients

All can be downloaded from the BIR website
