HiRes Ultra 3D Cochlear Implant - now MRI compatible (conditional up to 3 Tesla MRI)

On August 30, 2018, Advanced Bionics announced its new HiRes Ultra 3D cochlear implant that is MRI compatible (up to 3 Tesla MRI strength) without removal of the implant's internal magnet and without the need for a head bandaging protocol during MRI scanning. The new internal magnet design results in no pain and no need for special head orientation during MRI scanning.

Redesigned 3D Internal Magnet

The Ultra 3D cochlear implant magnet provides 3D magnetic field alignment and eliminates the need for surgical removal of the magnet, head bandaging, or restrictions on head orientation during MRI scanning in order to permit a a high-resolution MRI study.

The unique 3D magnet is composed of four rotatable magnet rods encased in a revolving disc that allows the magnet to provide alignment with MRI magnetic fields in all three dimensions (X, Y, and Z axes). The magnet is removable and can be replaced with a non-magnetic spacer through a small incision made prior to an MRI study.

HiRes Ultra 3D magnet that has been tested to keep working even after two hundred 3.0 Tesla MRI routines.


The unique cylindrical magnets provides magnetic field alignment and adjusts to variations in the MRI magnetic field.


Conditional MRI issues with the HiRes Ultra 3D cochlear implant include:

  • The external sound processor and headpiece must be removed before entering a room containing an MRI scanner.
  • 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.
  • For other MRI situations, i.e. if the recipient has two different types of Advanced Bionics Cochlear Implants (e.g. HiRes Ultra 3D and HR90k Advantage), the recipient must inform the MRI professional of the type of implants. If the recipient is not sure of the implant type, please contact the recipient’s cochlear implant clinic, the local AB office, or contact Advanced Bionics Technical Support.

    NOTE: MRI procedures are contraindicated for CLARION (C1 and CII) cochlear implant recipients. For information regarding MRI use with HiRes 90K, HiRes 90K Advantage, and HiRes Ultra cochlear implants, please contact Advanced Bionics Technical Support.

    NOTE: MRI safety was evaluated only for the HiRes Ultra 3D. Interactions between non-Advanced Bionics implants and the HiRes Ultra 3D during MRI are unknown.
  • The recommended minimum duration of time post implant surgery prior to undergoing an MRI scan is 2 to 4 weeks in order to allow any inflammation to subside.
  • An MRI scan is not recommended if the patient has a fever.

Cautions include:

  • During the MRI procedure, you may experience pain, pressure, or discomfort. If this occurs, please notify your physician.  
  • Please consult with your physician prior to an MRI to determine if the benefits of an MRI are worthwhile over other imaging techniques.
  • In case of two different implant types or models, MRI safety criteria that is most restrictive of the two implant types must be applied at the discretion of a qualified MRI professional.

Testing has demonstrated that the HiRes Ultra 3D cochlear implant is MR Conditional. Unilateral and bilateral recipients with this device with magnet in place can be safely scanned in a horizontal closed bore quadrature coil MR system meeting the following conditions:    

MRI Field Strength



Maximum Spatial Field Gradient 20 T/m 20 T/m
RMS Gradient Field 34.4 T/s 34.4 T/s
Peak Slew Rate 200 T/m/s 200 T/m/s

Maximum Whole Body Averaged SAR

2.0 W/kg 2.0 W/kg
Maximum Head Averaged SAR 3.2 W/kg 2.6 W/kg

When tested under scan conditions defined above, the HiRes Ultra 3D cochlear implant produced a maximum temperature rise of <3˚C after 15 minutes of continuous scanning.

Note: During the scan, patients might perceive auditory sensations. Adequate counseling of the patient is advised prior to performing the MRI. The likelihood and intensity of the auditory sensations can be reduced by selecting sequences with a lower Specific Absorption Rate (SAR) and slower gradient slew rates.


Imaging Artifacts at 3.0T and 1.5T MRI Field Strengths

Table A: Artifact at 3.0T MRI Field Strength



Artifact Range

Unilaterally In Place 5.5 - 6.9 cm
Unilaterally Removed 1.4 - 4.2 cm
Bilaterally In Place 6.1 - 7.4 cm


Removed 1.9 - 6.9 cm


Table B: Artifact at 1.5T MRI Field Strength



Artifact Range

Unilaterally In Place 4.1 - 6.5 cm
Unilaterally Removed 2.4 - 3.2 cm
Bilaterally In Place 5.7 - 8.2 cm


Removed 3.4 - 4.1 cm

Note: For cases that would clinically benefit from reduced device artifact (for example, some head or neck scans), the internal magnet is surgically removed and possibly replaced with a Temporary Non-Magnetic Plug before the recipient undergoes an MRI procedure. The HiRes Ultra 3D cochlear implant can withstand 5 replacement cycles.

Advanced Bionics Corporation (ABC) has announced its newest cochlear implant sound processor, the Neptune. The Neptune is the world's first waterproof CI sound processor and has been approved by the U.S. FDA.

Now, patients being implanted with an ABC cochlear implant will have the choice of wearing either the Harmony (non-waterproof) or the Neptune (waterproof) sound processors. If hospital practices and insurance reimbursement is supportive, patients will have the opportunity to purchase dual-sound processor systems i.e. two Harmony SP's, two Neptune SP's, or one of each.

Being waterproof, one can swim or bathe with the Neptune! Hearing is still delivered during these important times, especially for babies and young, active children.

The Neptune is a free-style design so that nothing is worn on the outer ear. The Neptune may be worn in the hair, on the arm, under their collar, or in their pocket without compromising hearing performance.

The Neptune design is tough and rugged. It carries an IP68 rating that offers maximum protection against solid particles and various forms of moisture. CI patients now have an opportunity to hear in all weather, all sports, and all terrain.

Neptune includes ABC's ClearVoice™, HiRes Fidelity 120™, and AutoSound™ technologies.

Neptune's Features:

  • Swim with the Neptune
  • Bond during bath time
  • Freestyle Design
  • ClearVoice™, HiRes Fidelity 120™, and AutoSound™ technologies
  • Removable controls
  • Flexible wearing options
  • Fashion-forward colors
  • Off-the-Shelf AAA battery
  • Convenient wearing accessories
