title: MRI compatibility and safety of cochlear implants.
abstract: The increasing magnetic strengths used for magnetic resonance imaging (MRI) combined with a greater number of MRI patients with cochlear implants (CIs) raises possible safety issues. This paper reviews the interactions between MRI and CI, and assesses MRI compatibility and safety of CIs at 0.2, 0.3, 1.0, 1.5 and 3.0 tesla (T). In a word, CIs represent a significantcontraindication to MRI. Only after careful evaluation of the individual risk and careful preparations can an MRI be safely performed.
