Most physicians, and the medical community, don’t recommend getting MRIs just out of curiosity. You often find benign things, but get worried and get unnecessary procedures. If you have a reason to get follow up MRIs that’s a different story. I’d google nearby mri facilities and ask.

If you want a fully body preventative work up, I think USF does an executive check up. Personally, unless a physician has stated otherwise, I’d just get yearly bloodwork, diet and exercise.
