Cochlear™ Nucleus® Implants:
Designed for access to MRI scans

Cochlear™ Nucleus® Implants have been designed with MRI access in mind for two decades. Access to MRI scans vary based on the generation of the device with our legacy products having more conditions to follow for scans. Details are outlined in our MRI Guidelines.

Cochlear Nucleus Profile™ Plus, the latest implant offering, provides access to MRI at 1.5T and 3.0T with magnet in place and no head wrap. The Profile and CI24RE implants are approved for MRI scans. MRI access is available for the majority of Nucleus implant recipients, but the specific conditions and access differ based on implant type.

Each cochlear implant generation has specific guidelines that need to be followed. The approved scan types for implants are as follows:

Implant Type

MRI Status at 1.5 T

MRI Status at 3.0 T

Profile Plus (CI632, CI622, CI612)

Magnet in place with no MRI Splint Kit

Magnet in place with no MRI Splint Kit

Profile (CI532, CI522, CI512, ABI541)

Magnet in place with use of MRI Splint Kit

Magnet must be surgically removed

Freedom (CI422, CI24REH, CI4RE(CA), CI4RE(ST), ABI24M)

Magnet in place with use of MRI Splint Kit

Magnet must be surgically removed

CI24R, CI24M

Magnet in place with use of MRI Splint Kit

Magnet must be surgically removed

CI11+11+2

Magnet in place with use of MRI Splint Kit

Contraindicated for MRI

CI22M with removeable magnet

Magnet in place with use of MRI Splint Kit

Contraindicated for MRI

CI22M without removeable magnet

MRI Splint Kit Instructions

For those patients requiring a splint kit, you can order a kit by calling 1-866-210-9217, Option 2. To learn how to apply the kit, see the video and instructions below to further support the information found in the guidelines.

Most Nucleus implant generations (see indications for specifics) are approved for MRI scans at 1.5 Tesla without having to surgically remove the implant magnet. To help prevent discomfort or dislodgement of the implant magnet during an MRI scan, which some people may experience, we have also made available the Cochlear™ Nucleus® Implant Bandage and Splint Kit for MRI (MRI Kit).

Note: Profile Plus does not require the use of the MRI Splint Kit.

MRI for Cochlear™ Baha® Systems

For the Baha Connect System, as long as the sound processor is removed, you can have an MRI scan without any additional risk. There could be a resulting shadow in the image.

The Baha Attract System includes a magnet implanted under the skin and is conditionally approved for MRI scans up to 1.5 Tesla. There may be a significant shadow effect for scans of the head. For access to higher strength scans or to reduce the shadow effect the magnet can be temporarily removed in a straightforward procedure. Baha sound processors should be removed prior to any MRI scan.

Implant Type

MRI Status at 1.5 T

MRI Status at 3.0 T

Baha Connect

MRI Guidelines for Cochlear™ Osia® System

Osia was designed with the same technology that has allowed for access to MRI for over two decades in Cochlear Nucleus Implant recipients. This key design feature allows for removal of the magnet.

The Osia 200 implant was cleared as MRI Conditional at 1.5T and 3.0T with the implant magnet removed.

Implant Type

MRI Status at 1.5 T

MRI Status at 3.0 T

Osia (OSI200 with BI300)

Magnet in place with use of MRI Splint Kit

Magnet should be surgically removed
