Well no one should get MRIs with contrast for fun. Moreover, doctors regularly use contrast off label.
My dad was in this industry when nsf first came out. We would be dragged along to after hours family things at conferences. Doctors openly said they gave contrast off label at dosages not approved by the FDA for organ systems not approved by the Fda. Even children. I'm sure they had their reasons, but I'm also sure they never disclosed the possibility of nsf and just told parents their kids needed it, because they admitted it.
