Dimensions of artefacts caused by cochlear and auditory brainstem implants in magnetic resonance imaging.

The aim of the study was to investigate the extent of MRI artefacts due to the magnet of selected auditory implants. Artefacts of the Synchrony cochlear implant at 1.5 T as well as at 3 T MRI devices were examined in cadavers and compared to the artefacts in MRI scans at 1.
