MRI Warning

Do not allow patients with a HiRes 90K or 90K Advantage cochlear implant to be in the area of an MRI scanner unless the following conditions have been met:

  • The internal magnet is surgically removed and possibly replaced with the temporary non-magnetic plug before the patient undergoes an MRI procedure.
  • The external sound processor and headpiece are removed before entering a room where an MRI scanner is located.
  • 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.
  • It is recommended not to have an MRI scan if the patient has a fever.
