Do not allow patients with a HiRes Ultra cochlear implant to be in the area of an MRI scanner unless the following conditions have been met:
The bandaging protocol [Refer to the MRI Antenna Coil Cover (CI-7521) IFU for details] recommended by Advanced Bionics is followed when the patient undergoes an MRI procedure with the magnet left in place, or
For cases that would clinically benefit from reduced device artifact (for example some head or neck scans), the internal magnet is surgically removed and possibly replaced with the temporary nonmagnetic plug before the patient undergoes an MRI procedure.
The external sound processor and headpiece are MR Unsafe and must be removed before entering a room containing an MR scanner.
The recommended minimum duration of time post implant surgery prior to undergoing an MRI scan is 2 to 4 weeks in order to allow any inflammation to subside.
An MRI scan is not recommended if the patient has a fever.
