I have had several mri, some very long and some that just seem long. I am extremely claustophobic, so i let the dr know before hand and they usually give me a valuim to take before the test. sometimes they give me one when i get there that is a quick disolving pill placed under the sun. By nighttime i am usually in pain or at least very stiff. I do not mind so much when they do my neck as it does not take so long, the back takes longer since it is a thicker area.
My first mri was in 1982, it was new at the hospital. I had just had my dtr and had problems. I had staples in my stomach from a c section. i remember them telling me there were going to take them out while i was on the table, as they did not know how they would react in the machine.
I try to take my mind off the machine. That time i sung nursery rhymes in my head now i make lists or something like that. it helps to distract yourself.
