The Neuro Zti implant is MR Conditional with 1.5 Tesla scans with the magnet in place for both body and head scans.

The implant has been designed to ensure this type of scan is safe and does not produce "magnet flip"3 as the magnet is held firmly in place by the rigid implant structure2. This means it can’t dislodge and remains locked in even after multiple MRI exams, while the implant itself remains stable throughout the MRI scan thanks to a unique screw fixation system that securely attaches it to the bone.

Neuro Zti – easy magnet removal

The Neuro Zti is is designed for easy magnet removal under local anesthesia with only a small skin incision. The implant is attached using screws and not drilled into the skull, which makes the magnet easily accessible. With the dedicated Oticon Medical surgical tool, the magnet is removed in a few steps and can then be replaced again after the scan.

  • Instructions For Use
