To capture practice and opinions around the current clinical use of MRI in patients with cochlear implants (CIs), and to characterise patient progression from referral to image reporting.
An online survey recruited 237 healthcare professionals between 9 December 2019 and 9 September 2020. Descriptive statistics and informal thematic analyses were conducted.
Respondents estimated that approximately 75% of CI users referred for an MRI proceeded to image acquisition, of which ~70% of cases comprised image acquisition on the head and the remaining cases on another area. They estimated that the proportion of these images that were usable was 93 and 99%, respectively. Confidence in most processes was high, with at least two-thirds of respondents reporting to be very or somewhat confident in obtaining consent and acquiring images. Conversely, fewer than half the respondents had the same confidence when splinting and bandaging the implant and troubleshooting any issues arising. Patient safety was rated of paramount importance, with patient comfort a clear second and image quality third.
These findings highlight the need for consistent publication of clear, succinct, and standardised operating procedures for scanning patients with CIs and the requirement for regular training of radiographic and radiological healthcare professionals to address the heterogeneity of devices available.
There is a need to improve the communication to radiography and radiology personnel regarding the nature of CIs, the heterogeneity of devices in existence, and the key differences between them. CI users risk being underserved by diagnostic medical imaging.
了解当前在接受人工耳蜗植入术（CI）的患者中使用 MRI 的实际情况和意见，以及描述患者从转诊到影像报告的进展情况。
于 2019 年 12 月 9 日至 2020 年 9 月 9 日期间，通过在线调查招募了 237 名医疗保健专业人员。采用描述性统计和非正式主题分析方法。
调查对象估计，大约有 75%的 CI 使用者接受 MRI 检查，其中约 70%的病例包括头部成像，其余病例则包括其他部位的成像。他们估计这些图像的可用性比例分别为 93%和 99%。大多数流程的信心较高，至少有三分之二的调查对象报告对获得同意和获取图像非常有信心或有一定信心。相反，不到一半的调查对象对固定和包扎植入物以及解决任何出现的问题有同样的信心。患者安全被认为是至关重要的，患者舒适度是明确的第二位，图像质量是第三位。
这些发现强调了需要为扫描接受 CI 治疗的患者制定一致的、简洁明了的和标准化的操作程序，并需要对放射学和放射医疗保健专业人员进行定期培训，以解决现有设备的异质性问题。
需要改善与放射学和放射科人员的沟通，让他们了解 CI 的性质、现有设备的异质性以及它们之间的关键差异。如果不能妥善处理，CI 用户可能会面临诊断性医疗成像服务不足的问题。
