MRI compatibility issues in otology.
OBJECTIVE
The increasing magnet strengths used for MRI scanning combined with a greater number and variety of otologic prostheses can lead to possible safety issues. This review examines the specific issues and the conclusions of 33 referenced studies examining those issues.


RESULTS
Variability of interactions between otologic implants and MRI scanners requires specific considerations for individual prostheses and magnet strengths. Recommendations are proposed in the referenced studies.


CONCLUSIONS
When a patient with an otologic prosthesis requires an MRI scan, options exist to help assure patient safety.
