Absence of radiofrequency heating from auditory implants during magnetic resonance imaging.
Chou CK, McDougall JA, Can KW · 1995
View Original AbstractAuditory implants showed no heating during MRI scans at 64 MHz, suggesting these medical devices are safe during magnetic resonance imaging.
Plain English Summary
Researchers tested whether auditory implants (devices that help deaf people hear) would cause dangerous heating during MRI scans by using a realistic human phantom head and measuring temperatures with thermal imaging and fiber-optic probes. They found no observable heating around the implants during a 26-minute MRI scan designed to produce maximum radiofrequency exposure. This finding is important for patient safety, as it suggests people with these hearing implants can safely undergo MRI scans without risk of tissue damage from overheating.
Study Details
The possibility of tissue heating due to an auditory brainstem implant (ABI) or a modified cochlear implant (CI) during magnetic resonance imaging (MRI) of the head was tested on a full-sized human phantom using a realistic phantom head consisting of simulated skull, brain, and muscle.
Dielectric properties of the brain, muscle, and bone materials were similar to those of human tissue...
Results showed no observable heating associated with the ABI and the modified CI during worst-case M...
