Since 1998, Cochlear™ Nucleus® implants have been built intentionally with MRI safety in mind. Our implants have a unique design that ensures an easy-to-remove magnet, when necessary. With the magnet in place (using provided MRI splint kit), the implant allows for MRI compatibility with up to 1.5 Tesla (T). When the magnet is removed, Nucleus implants allow for MRI compatibility with up to 3.0T. Although MRIs can range in strength from 0.2T to 7.0T, 1.5T is the most commonly used. In fact, 8 out of 10 MRIs are done with 1.5T strength MRI machines.1
Our easy and safe magnet removal is the gold standard for MRI patient safety and reliability of images during head and neck scans. Removing the implant magnet is a simple process, which minimizes artifacts in the MRI and the risk of patient discomfort. Cochlear’s history of implant design allowing magnet removal ensures recipients have access to MRI today as well as into the future, even as the standard MRI machines continue to increase in Tesla strength.
For patients who require serial MRIs, Cochlear offers an optional magnet-free system, which utilizes adhesives for the external portion of the device. This type of system can be beneficial for patients with comorbidities.
