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.
了解当前人工耳蜗（CI）使用者群体中对于进行磁共振成像（MRI）必要性的看法。
CI使用者的磁共振成像（MRI）检查常伴有严重不适和磁体移位。
于2020年7月22日至9月13日对310名CI使用者进行了一项全球在线调查。
只有55%的受访者被告知其CI型号是否可以进行MRI检查。31%的受访者在决定是否接受CI时考虑了MRI，28%的受访者在决定使用哪种CI型号时考虑了MRI。64%的受访者表示如果需要进行MRI检查会担心其CI，相比之下，29%的受访者表示担心与CI无关的问题。当考虑到磁体移除、夹板固定、包扎、局部麻醉、持续不适、无法使用CI或因CI导致图像质量下降时，接受MRI检查的意愿降低。最具影响力的单一因素是CI受损的可能性（63%）。59%的受访者会考虑进行小手术，将其固定磁体升级为旋转设计的磁体。
这些发现凸显了CI使用者对MRI看法的异质性。
我们提出了几个机会，以改善向CI使用者传播当前准确的MRI相关信息的情况。
