The external processors of these devices are MR Unsafe. Of the implants tested, middle ear ossicular prostheses, including stapes prostheses, except for the 1987\u00a0McGee prosthesis, are MR Conditional for 1.5\u2010Tesla (and many are approved for 3\u2010Tesla) MR systems. Cochlear implants with removable magnets are approved for patients undergoing MRI at 1.5 Tesla after magnet removal. The MED\u2010EL PULSAR, SONATA, CONCERT, and CONCERT PIN cochlear implants can be used in patients undergoing MRI at 1.5 Tesla with application of a protective bandage. The MED\u2010EL COMBI 40+ can be used in 0.2\u2010Tesla MR systems.
