Abstract
The number of patients with cochlear implant increases each year. Most of these patients may undergo MR imaging up to 1.5Â Tesla, based on safety recommendations from each of the manufacturers. All external components should be removed for the examination. For three manufacturers providing about 85Â % of all implanted devices in Europe, the internal components may be left in place and covered by an external bandage. Strict protocol guidelines must be implemented, especially head positioning in the magnet and within 30Â cm from the bore opening. A single manufacturer, providing about 15Â % of implanted devices, recommends surgical removal of the internal magnet prior to MR imaging.
