Synopsis

A cochlear implant (CI) contains a magnet implanted under the scalp. MRI of CI users is associated with safety concerns, significant discomfort, and image distortion. A CI placed under a swimming cap is a feasible tool for observing the effect of CI location on image usability within a single subject and potentially informing surgical planning. 35-70% of radiological features in the head were deemed unaffected by the implant. Online survey results highlight the need for consistent publication of clear, succinct, and standardised information for healthcare professionals and CI users. CI user consultation is scarce, meaning their views are often neglected.
