Cochlear implant user perceptions of magnetic resonance imaging

To characterise opinions about needing to undergo MRI within the population of current cochlear implant (CI) users.

Magnetic resonance imaging (MRI) of CI users is often associated with severe discomfort and magnet displacement.

A global online survey of 310 CI users was conducted between 22nd July and 13th September 2020.

Only 55% of respondents had been told whether their model of CI could undergo MRI. 31% of respondents considered MRI when deciding whether to receive a CI, and 28% when deciding which CI model to have. 64% reported concerns related to their CI if needing MRI compared to 29% reporting concerns unrelated to their CI. Willingness to undergo MRI reduced when considering magnet removal, splinting, bandaging, local anaesthesia, lasting discomfort, an inability to use their CI, or a reduction in image quality because of their CI. The single most influential factor was the possibility of damaging their CI (63%). 59% of respondents would consider minor surgery to upgrade their retaining magnet to one of a rotating design.

These findings highlight the heterogeneity of CI users' opinions about MRI.

We suggest several opportunities for improving the dissemination of current and accurate MRI-related information for CI users.
