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.

Nucleus Profile™ and Nucleus Freedom® implants are designed to allow for access to MRI with conditional approval, with specific approval of 1.5 T with magnet in place with the splint kit and 3.0 T with the magnet removed.

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:

MRI Splint Kit Instructions:

For those patients requiring a splint kit, you can order a kit by calling 877-883-3101 Option 1. To learn how to apply the kit, see the video and instructions below to further support the information found in the guidelines.

Cochlear Nucleus Profile CI500 and CI24RE Series implants 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).

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.
