I was scheduled yesterday for MRIs on both legs. I was supposed to put one leg at a time in this new machine and keep it there for 45 min. without moving!!!! That would be a total of one hour and a half. I told them there was no way and so they have rescheduled me for the machine that you lie down in. I have decided to do each leg on a different day as I have no idea how I possibly can do it for the 45 min. time allowed for one, not to mention I have to do it twice. Maybe I need some kind of pill to knock me out or totally relax me. What have others done? I can not keep my legs in a sitting position or other position for longer than a few minutes. I usually do not take meds other than ibupropin as I am too sensitive to meds. I would appreciate any input. Thanks.
