MRI warnings

Do not allow patients with a HiRes™ cochlear implant to be in the area of an MRI scanner unless the following conditions have been met:

  • The bandaging protocol recommended by Advanced Bionics is followed when the patient undergoes an MRI procedure with the magnet left in place or,
  • The internal magnet is surgically removed and possibly replaced with the Magnet Insert Dummy before the patient undergoes an MRI procedure.
  • The external sound processor and headpiece are removed before entering a room where an MRI scanner is located.
  • MRI preparations must be conducted outside of the MRI room.
  • Verify that the implant, or both implants if bilaterally implanted, are compatible for conducting an MRI before proceeding. Failure to do so can lead to device movement, device damage, magnet movement, patient discomfort, or trauma and pain to the patient.
  • MRI procedures are contraindicated for CLARION (C1 and CII) Cochlear Implant recipients.


Caution: The bandaging protocol with use of the MRI Antenna Coil Cover was developed and approved to prevent magnet displacement and counteract magnet torque during a 1.5T MRI procedure, but some discomfort and pain at the implant site may still be experienced. Please consult with your physician if this is an issue.

Caution: If discomfort persists following an MRI, please notify your physician.

Caution: Failure to secure the MRI Antenna Coil Cover and internal magnet in place during MRI may result in magnet displacement or the need for surgical revision.

Caution: Please consult with your physician prior to MRI to determine if the benefits of MRI are worthwhile over other imaging techniques
