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 1.5 T and 3.0 T with magnet in place. The Profile and CI24RE implants are approved for MRI scans with magnet surgically 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 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.
