My first MRI I had IV sedation with twilight and 240 mcgs of fentenyl. I continued to freak out. On my second MRI they knocked me out completely. Now I need another one.(I have MS)And my neurologist no longer has admitting rights to the hospital. They have suggested IV Valium sedation, at their main location in another town
Anyone have experience with this? Doctor, what is your opinion?

Thank you
