ABSTRACT
Background:
There are many patients with cochlear implants (CIs) who need to undergo an MRI examination. Due to recent develop-ments in science and medicine a CI is no longer a contraindication for an MRI.
Material and Methods:
The review is based on scientific publications found in Google Scholar and PubMed databases.
Results:
The problems with carrying out an MRI examination on a patient with a CI are the low quality of the image and possible head pain when the MRI machine is operating. Demagnetization or displacement of the CI magnet can also occur. Normally, special procedures are required, including removing all external parts of the implant system before the MRI, and bandaging of the head before the procedure. Implants compatible with new generation magnets exist and they allow an MRI to be performed without removing magnetic materials from the CI.
Conclusions:
There are still many limitations in performing an MRI with CI patients; however the risk of implant damage can be significantly decreased. Patient comfort during the examination can also be increased.
