MRI is a widespread and greatly helpful diagnostic tool, yet its use on cochlear implant patients is restricted by the presence of an inner magnet. We report on a case of magnet dislodgment after 1.5T MRI in a 31-year-old female with a Hi-Res 90K cochlear implant. In this case, it was possible to implement an alternative, totally noninvasive approach based on an external manual repositioning rather than a surgical procedure of the displaced magnet.
MRI 是一种广泛应用且极具帮助的诊断工具,但由于内置磁铁的存在,其在人工耳蜗植入患者中的使用受到限制。我们报告了一例 31 岁女性使用高分辨率 90K 人工耳蜗植入后在 1.5T MRI 检查中发生磁铁移位的病例。在这种情况下,可以采用一种替代的、完全非侵入性的方法,即通过外部手动复位而非手术复位来处理移位的磁铁。
