Summary
Cochlear implants are used for profound deafness. This study discusses MRI safety for cochlear implant users, finding safe imaging is possible with specific conditions and scanners.
Area of Science:
- Otolaryngology
- Medical Imaging
Background:
- Profound bilateral deafness is treated with cochlear implants.
- Magnetic resonance imaging (MRI) is an increasingly vital diagnostic tool.
- Cochlear implant recipients are likely to require MRI scans in their lifetime.
Purpose of the Study:
- To assess the safety of magnetic resonance imaging (MRI) for patients with cochlear implants.
- To discuss potential interactions between cochlear implants and MRI procedures.
- To outline conditions for safe MRI examinations in cochlear implant wearers.
Main Methods:
- Review of major and potentially problematic interactions between cochlear implants and MRI.
- Focus on the C40/C40+ cochlear implant system as a case study.
- Analysis of conditions required for safe MR examinations.
Main Results:
- Identified significant interactions between cochlear implants and MRI.
- Established specific conditions for safe MRI procedures.
- Demonstrated that safe MR imaging is achievable for C40/C40+ systems.
Conclusions:
- MRI safety for cochlear implant users is a critical consideration.
- Safe magnetic resonance imaging is possible for C40/C40+ systems at 0.2, 1.0, and 1.5 Tesla.
- Guidelines for safe MRI conduct with cochlear implant wearers are essential.

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...
