In principle MR systems may be used only together with compatible equipment.
The following definitions apply:
! The MR system or equipment should not be used adjacent to other equipment, if adja-
cent or beside use is necessary, the equipment or system should be observed to verify
normal operation in the configuration in which it will be used.
MR-safe The device or implant is completely non-magnetic, non-electri-
cally conductive, non-RF reactive and indicates no known haz-
ards in all MRI environments.
MR-conditional The device or implant may contain magnetic, electrically con-
ductive or RF-reactive components. These devices are safe while
being used in proximity to the MRI, provided the conditions for
safe operation are defined and observed. Similarly, MR-condi-
tional devices (for example, RF communications equipment)
may present hazards as well. Please observe the manufacturer’s
operator manual to avoid potential hazards and injuries.
MR-unsafe An item that is known to pose hazards in all MR environments.
