I commented to windyshores about the open MRI as an alternative to a closed one, but when I called the open MRI lab, the tech said she didn't even know what decibels the MRI was...I don't understand why none of the techs are in the least concerned with the hearing issues of their patients and what effect an MRI may have on them. I am thinking about calling the head of our local hospital and asking for them to purchase an MRI approved set of headphones for their patients. I saw them on Amazon.
