Risks: Thermal, Displacement, Device Malfunction
- Static magnetic field strength up to and including 1.5T.
- All external removable components must be removed. Note that the patient will not be able to hear.
- Wrap the head using an Ace bandage type wrap (NO metal clips) and splint using a credit card-sized piece of plastic or thin cardboard. Do NOT use a credit or other type or card that contains a magnetic strip or chip.
- In general, Cochlear Implants are NOT safe for MRI, unless specifically approved as MR conditional.
- Warn the patient that he or she will feel pulling or pressure, but if there is any pain, heating or burning, the patient should alert the tech immediately.
- While unlikely, it is possible that the MRI could cause the implanted magnet to move and this could require surgery to correct.
- After the scan, interview the patient to make sure all is OK and document this in a note in PACS or Epic.
Bottom Line: MRI Permissible if all conditions are met
