CT Scan Contrast

[Petloy]

Hi Dr. Nagler,

Will the CT Scan spike or exacerbate tinnitus?

Thanks,
Peter

Peter, a CT scanner is relatively quiet. You do not need earplugs in a CT scanner like you do in an MRI scanner. Neither the oral contrast nor the iodinated intravenous contrast used in a CT scanner causes auditory damage. I have heard of very rare instances in which tinnitus is exacerbated as a result of the iodinated intravenous contrast, and even in those unusual situations the exacerbation is transient.

Hope this helps.
