I really hope things work out. I know when My like daughter-in-law used to have to have MRI's and other testing that was enclosed. She had to have me come with her and talk her through it. It was anxiety but in her case something that had happened in her teens that she had to deal with. So we always told the
places ahead of time, and if they had an problem with me being in the room., we talked to her doctor and got another site.

And a couple times the test had to be stopped, her to relax and started again.
I know one time we never got it finished. I always drove her also.
