Split the MRI ?
Do you guys schedule separate appointments for Brain and Spine MRI scan?
I used to do it all in one session but it becomes increasingly uncomfortable to lay still on the surfboard style bed for almost two hours (if you get the contrast scan on top of the regular one).

No. I do it all at once but I haven't had discomfort. Does Ativan help? I am claustrophobic, and it makes me care less, so it's possible that I don't notice being uncomfortable
It’s more a pain on my shoulder blades and the back of my head. Possibly due to a lack of padding but when they set me up initially it’s fine but after an hour it gets painful and you shouldn’t really move.
