MRI at your convenience

MRI scans are a standard medical diagnostic technique and Nucleus implants are designed to fit with your lifelong medical requirements. If you ever need a medium strength MRI up to 1.5 Tesla, you can rest assured that your Nucleus implant allows you to safely undergo the scan with your magnet in place*. And if you need a high-powered MRI up to 3 Tesla*, the removable magnet makes that possible in a simple outpatient procedure too.
