OBJECTIVE
To observe the effects of magnetic resonance imaging scans in Vibrant Soundbridge 503 implantees at 1.5T in vivo.
METHODS
In a prospective case study of five Vibrant Soundbridge 503 implantees, 1.5T magnetic resonance imaging scans were performed with and without a headband. The degree of pain was evaluated using a visual analogue scale. Scan-related pure tone audiogram and audio processor fitting changes were assessed.
RESULTS
In all patients, magnetic resonance imaging scans were performed without any degree of pain or change in pure tone audiogram or audio processor fitting, even without a headband.
CONCLUSION
In this series, 1.5T magnetic resonance imaging scans were performed with the Vibrant Soundbridge 503 without complications. Limitations persist in terms of magnetic artefacts.
目的
观察1.5T磁共振成像扫描对体内植入Vibrant Soundbridge 503的患者的影响。
方法
在一项对5名植入Vibrant Soundbridge 503患者的前瞻性病例研究中，分别在佩戴和不佩戴头带的情况下进行1.5T磁共振成像扫描。使用视觉模拟量表评估疼痛程度。评估与扫描相关的纯音听力图和音频处理器适配变化。
结果
在所有患者中，即使不佩戴头带，进行磁共振成像扫描时也未出现任何疼痛程度、纯音听力图或音频处理器适配的变化。
结论
在本系列研究中，对植入Vibrant Soundbridge 503的患者进行1.5T磁共振成像扫描未出现并发症。在磁伪影方面仍存在局限性。
