New Safety Definitions for MRI as Defined by International
MR SAFE:
An item that poses no known hazards resulting from exposure to any MR
environment. MR SAFE items are composed of materials that are electrically
nonconductive, non-metallic, and nonmagnetic.
MR CONDITIONAL:
An item with demonstrated safety in the MR environment within defined
conditions. At a minimum, address the conditions of the static magnetic field, the
switched gradient magnetic field and the radiofrequency fields. Additional
conditions, including specific configurations of the item, may be required.
Supplementary marking – additional information that, in association with
marking as "MR CONDITIONAL," states via additional language the conditions in
which an item can be used safely within the MR environment.
MR UNSAFE:
An item which poses unacceptable risks to the patient, medical staff or other
persons within the MR environment.
