Abstract

Objective: Many patients with cochlear implants (CI) and auditory brainstem implants (ABI) require magnetic resonance imaging (MRI) following implantation. This study explores the patient experience of MRI, identifying factors associated with pain, and the effect of interventions designed to enhance comfort and safety.

Methods: A prospective observational case series from a tertiary referral unit. Tight head bandaging ± local anaesthetic injection (devices with non-MRI-compatible magnets) or observation alone (implants with MRI-compatible magnets) were employed for 1.5 T MRI of consecutive adult patients with CI or ABI without magnet removal. Pain was recorded via visual analogue scale (1 = no pain, 5 = extreme pain) at three time points; (1) baseline, (2) head bandage applied (3) during scanning. Patient age, device type, body area imaged and total scan time were recorded as variables, alongside adverse events.

Results: Data were collected for 227 MRI scans (34 patients with ABI, 32 with CI). In patients managed with bandaging, pain score after bandaging but prior to scanning (median 2.2) did not differ from pain during scanning (2.1), but both were significantly higher than baseline (1.4, both P ≤ 0.001). Scanning areas other than the head/cervical spine was associated with higher pain scores (P = 0.036). Pain during MRI differed between different manufacturers implants (P ≤ 0.001). Adverse events occurred in 8/227 scans (3.5%), none occurring with devices containing an MRI-compatible magnet.

Conclusion: MRI scanning with auditory implant magnets in situ is safe and well tolerated by patients.

听觉植入者接受核磁共振成像的经验:与疼痛相关的因素。

目的:许多人工耳蜗(CI)和听觉脑干(ABI)植入患者在植入后需要进行磁共振成像(MRI)检查。本研究探讨了患者的MRI体验，识别与疼痛相关的因素，以及旨在提高舒适度和安全性的干预措施的效果。方法:来自三级转诊单位的前瞻性观察病例系列。对连续的成年CI或ABI患者进行1.5 T MRI检查时，采用头部紧密包扎±局部麻醉注射(非MRI兼容磁铁装置)或单独观察(MRI兼容磁铁植入物)，不切除磁铁。通过视觉模拟量表记录3个时间点的疼痛(1 =无疼痛，5 =极度疼痛);(1)基线，(2)扫描过程中使用的头部绷带。患者年龄、设备类型、身体成像面积和总扫描时间与不良事件一起被记录为变量。结果:收集了227例MRI扫描数据(ABI 34例，CI 32例)。在接受包扎治疗的患者中，包扎后但扫描前的疼痛评分(中位数2.2)与扫描时的疼痛评分(中位数2.1)没有差异，但两者均显著高于基线(1.4，均P≤0.001)。扫描头部/颈椎以外的区域与较高的疼痛评分相关(P = 0.036)。不同厂家植入物MRI疼痛差异有统计学意义(P≤0.001)。在8/227次扫描中发生了不良事件(3.5%)，使用含有mri兼容磁体的设备时没有发生不良事件。结论:原位听觉植入磁铁MRI扫描是安全的，患者耐受性良好。

期刊介绍： Cochlear Implants International was founded as an interdisciplinary, peer-reviewed journal in response to the growing number of publications in the field of cochlear implants. It was designed to meet a need to include scientific contributions from all the disciplines that are represented in cochlear implant teams: audiology, medicine and surgery, speech therapy and speech pathology, psychology, hearing therapy, radiology, pathology, engineering and acoustics, teaching, and communication. The aim was to found a truly interdisciplinary journal, representing the full breadth of the field of cochlear implantation.
