Comfort MRI


*Recipients of the BONEBRIDGE Bone Conduction Implant may be safely MRI scanned without magnet removal at up to 1.5 Tesla following the conditions detailed in the instructions for use.

✓ No Surgery.
✓ No Discomfort.
✓ No Hearing Downtime.

Magnetic Resonance Imaging (MRI) is one of the most important diagnostic imaging tools. Magnetic fields are used to obtain detailed images of the inside of our bodies, enabling specialists to visualise and analyse structures and processes. The magnetic forces which are active during the MRI scan also affect magnets in the surrounding area, including magnets in implants such as BONEBRIDGE. Yet, undergoing an MRI with BONEBRIDGE is no problem. Find out how this is possible.

Why is BONEBRIDGE MR Conditional?

For an implant to be declared MR Conditional, a series of tests need to be conducted, including tests on torque, force, warming and noise. BONEBRIDGE has passed all those tests and can therefore be labelled MR Conditional up to 1.5 Tesla.

Two design features make this possible: Firstly, the implant is secured in the skull with screws and secondly, the patented magnet design prevents the magnets inside BONEBRIDGE from aligning with the magnetic field in the bore. Due to these features BONEBRIDGE users can safely undergo MRI scans without having to wear a head bandage or similar.


Certain preparations need to be made before every MRI. These are the same whether you have an implant or not:

  • You will be asked to undress and remove all metallic objects, such as glasses, earrings, piercings etc.
  • Also, please inform the staff about any metallic objects you might have inside your body, such as joint prostheses, metal splinter etc.

Is it complicated to get an MRI scan with BONEBRIDGE?

No - with BONEBRIDGE you have immediate access to MRI. You can simply make the appointment and undergo the examination. There is no need for surgery to remove the implant beforehand. Plan MRI MRI Scan

Is there anything to consider when undergoing an MRI with BONEBRIDGE?

Actually, you just need to make sure you take off your audio processor before entering the examination room and to hand your User ID Card to the staff. It contains the key conditions that make the examination with BONEBRIDGE possible. Other than that, the procedure is the same with BONEBRIDGE as it would be without a hearing implant.

What can you expect during the MRI?

  • It can actually get fairly loud during the scan. This is why you will be given some sort of noise protector, such as headphones, before the scan starts. Please be aware that you might experience some auditory sensation during the scan even if you do not wear your audio processor. This is due to the interference of the implant magnets with the magnetic field inside the bore. This is absolutely normal and will neither damage the implant nor your residual hearing.
  • Body temperature can rise up to 2°C during the scan. This effect is not related to BONEBRIDGE and does not harm the implant itself or the body.
  • A so-called image artefact will be visible around the implant site. This means that the area in close proximity to BONEBRIDGE will not be shown.

A user story: Having an MRI scan with BONEBRIDGE

Carmen C. (Spain) underwent an MRI with her BONEBRIDGE (BCI 601) implant. Read her experience below:

When I was a child I suffered from recurrent ear infections. This damaged my hearing so much that I finally lost it.

A couple of years ago, my ENT doctor recommended the BONEBRIDGE system. I must say, I’m glad I decided on the implantation: My quality of life has improved and it has become much easier for me to interact with people, in my private as well as in my professional life. I enjoy talking to my customers, listening to music and going to the cinema again. I own a business, so hearing and talking to people is really important.

The fact that BONEBRIDGE is MR-Conditional was definitely a reason for me to go for this implant. It is great that I did, because recently I had to undergo an MRI. The examination went well—there were no difficulties at all. I felt good during the whole scan and didn’t feel the implant at all. Everything was also good after the MRI: I can use my audio processor normally and don’t feel any difference when it comes to the sound quality or the attraction of the audio processor to my head.

MR images of Carmen C., BONEBRIDGE user, who had an MRI scan with her BCI 601. The BCI was implanted is in a retro-sigmoidal position. The images show the artefact around the implant. Areas which are in far proximity to the implant can be evaluated well.
