Thank you for responding. I spoke with the department of MRI application. I was told last year that sponge ear plugs are used and earmuffs. This is minimal protection for the ear canal since one has to listen to a roar of a jet plane for 1 hr. and 15 min. My point is.................clinics and doctors go to the extreme of protecting their credentials and insurance for the clinic. at the expense of the patient. A CT Scan I would accept of the head, but they want more. Many people I've talked to had cataract surgery without having an MRI. I feel I have become a specimen. My health is important in the right hands. Judy
