Parametric Assessment of the Effect of Cochlear Implant Positioning on Brain MRI Artefacts at 3 T.

Background: Brain magnetic resonance imaging in patients with cochlear implants (CIs) is impacted by image artefacts.

Hypothesis: The optimal positioning of the CI to minimize artefacts is unknown. This study aimed to characterize the dependence of the extent and distribution of the artefact on CI positioning.
