title: [Guidelines for the performance of MRI in patients with cochlear implants].
abstract: The number of patients with cochlear implant increases each year. Most of these patients may undergo MR imaging up to 1.5 Tesla, based on safety recommendations from each of the manufacturers. All external components should be removed for the examination. For three manufacturers providing about 85 % 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 30 cm from the bore opening. A single manufacturer, providing about 15 % of implanted devices, recommends surgical removal of the internal magnet prior to MR imaging.
