Signed responses from readers of the wire.
Audiologists and cochlear implant teams should note that MRI field strength and sequence selection meaningfully affect artifact size for the CS-30A implant; consult with radiology when ordering post-implant cranial MRI to choose the least artifact-prone protocol.
As cochlear implant recipients age and require neurological imaging, understanding how to minimize MRI artifacts protects diagnostic image quality and informs safe imaging protocols.
- 01Cochlear implant CS-30A generates artifacts in cranial MRI that vary by field strength and imaging sequence.
- 02Study used nonimplanted human clinical trials to isolate artifact effects across MRI conditions.
- 03Field strength (e.g., 1.5T vs. 3T) is a key variable in artifact magnitude.
- 04Findings can guide radiologists and cochlear implant teams in selecting optimal imaging protocols.
- 05Results published in Frontiers in Neurology (2026).
MRI artifact size from cochlear implant CS-30A varies depending on magnetic field strength.
