Performing MRI safely All external components of the Cochlear Osia System (e.g. sound processors, and related accessories) are MR Unsafe. The patient must remove all external components of their system before entering a room where an MRI scanner is located. Non-clinical testing has demonstrated that the Osia OSI200 Implant, in combination with the BI300 Implant, are MRI Conditional.1 Patients can be scanned at 1.5 T with the magnet in place or removed.

1. Preparation (Steps 1 - 2) 2. Bandaging (Steps 1 - 6) Prior to entering the MRI room and before removing the sound processor, ensure you have the contents of the MRI Kit available and within easy reach. NOTE Once the sound processor has been removed, the recipient will no longer be able to hear. To ensure greatest magnet attraction clear away as much hair as possible from the implant site. For recipients with long hair, it may be necessary to tie the hair up. 1.

3 T scans • Surgically remove the implant magnet before MR scans at 3 T. See OSI200 Implant Physician’s Guide for additional information. • Remove the sound processor before entering the MRI scan room. • The sound processor is MR Unsafe. • Static magnetic field of 3 T with the implant magnet surgically removed. In non-clinical testing, the maximum image artefact caused by the OSI200 Implant when imaged with a gradient echo pulse sequence scan in the axial plane (Table 3).
