MRI scans can range in strength from 0.2 T to 7.0 T, with 1.5 T being the most common.¹
Cochlear™ Nucleus® Implants: designed for MRI compatibility at 1.5 T and 3.0 T
We designed our latest Nucleus® Profile™ Plus Series Implant so you can have a routine 1.5 T MRI or a high-definition 3.0 T MRI without removing its magnet.2
This means no additional surgery, no need to wear a bandage in an MRI machine, no waiting for your scan and, most importantly, no unnecessary time without sound.
Nucleus Profile and Cl24RE/Freedom® implants are designed to be compatible for MRI at 3.0 T with a magnet removed and at 1.5 T with a magnet in place.2
Alternatives to MRI
Many people never need an MRI scan. For cochlear implant recipients, there is often other technology that can be used instead.
In a recent poll of radiology professionals, 85% agreed they have an alternative diagnostic tool for patients who cannot undergo an MRI due to having a device or implant with a magnet.3
More Cochlear ™ Implant recipients have MRI-compatible implants than any other cochlear implant brand
Cochlear was the first manufacturer to introduce cochlear implants with removable magnets in 1997. Our removable magnet means that a person implanted more than 20 years ago can still access today's MRI technology.
Committed to helping you
MRI compatibility is only one of many considerations when choosing a cochlear implant system.
Combined with our exceptional reliability record and industry-leading electrode technology, everything about our implant design supports our commitment to our recipients.
MRI for Cochlear Baha systems
For the Baha Connect System, as long as the sound processor is removed, you can be scanned by MRI. There will be some slight shadow effects caused by the implant and the abutment.
For the Baha Attract System, as there is an implanted magnet, the system is conditionally approved to 1.5 Tesla and there will be a large area of shadow.
For any additional strength MRI or to reduce shadow area, the magnet can be temporarily removed by a medical procedure. The sound processor should be removed for all MRI scans.
Prior to receiving an MRI, please consult with your Cochlear representatives about proper precautions.
