+ Importance of caution in the MRI environment
- The MRI magnet is very powerful, capable of moving and dislodging ferro-magnetic objects of all sizes towards the field, potentially causing significant injury and/or death.1-3
- Loose metallic objects can become projectiles in the presence of the strong static magnetic field, and are prohibited in the MRI magnet room1
- Some implants/devices are unsafe and may cause harm to the individual
- The magnet is always on, even if the facility has no power.
+ Access to the MRI environment
- Only MRI technologists and MRI radiologists are authorized to freely access the MRI control room and magnet room.
- Access for all other professionals is controlled by MRI technologists or MRI radiologists
- MRI-safety standards dictate that any individual entering the MRI magnet room must be carefully screened using an MRI safety screening form and undergo a verbal double check.1-3
- Performance of the screening is restricted to those with the necessary professional training in MRI-safety procedures.
- If there are any questions or concerns, the MRI technologist or radiologist should be consulted.
