ABSTRACT
OBJECTIVE:
The goal of this investigation was to provide evidence that magnetic resonance imaging (MRI) can be performed safely and effectively on cochlear implant patients who require diagnosis of additional diseases. STUDYDESIGN:
A retrospective study was performed over 5 years. In a total of 300 patients with cochlear implants at the authors' center, MRI was performed whenever it was medically indicated.SETTING:
All patients underwent scanning in a Philips Gyroscan T10-NT MRI machine, using commercially available Powertrac 3000 software. PATIENTS All patients with cochlear implants for whom MRI was indicated (n = 30) were included in this study. They had a wide variety of conditions necessitating MRI, including cervical discus prolapse, hypophyseal adenoma, epipharynx carcinoma, knee degeneration, parotid tumor, and preoperative evaluation for reimplantation and bilateral implantation.RESULTS:
No adverse effects from the MRI were reported by any of the patients. The cochlear implants all retained their function. All images were of diagnostic value. Because of the MRI, the patients did not need to undergo additional, more invasive and expensive diagnostic procedures. Examples of MRI images from 5 patients are shown.CONCLUSIONS:
MRI on cochlear implant patients, using the Med El Combi 40 and Nucleus mini 22 series at 1 Tesla, can be a safe procedure. Removal of any magnet is not necessary.
