| MRI_COMPATIBLE | MRI Compatible | A device 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. | X |
| MRI_SAFE | MRI Safe | The device 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. | X |
| MRI_UNSAFE | MRI Unsafe | The device poses unacceptable risks to the patient, medical staff or other persons within the MR environment. | X |
| UNSPECIFIED | Unspecified | Labelling does not contain MRI Safety Information - Information on the safety of using a device in a magnetic resonance (MR) environment has not been provided in the labelling by the labeller. | X |
