If you can find out the name of the contrast you'd be having I'm happy to look it up for you.
When I was in the ER at 2 days PP they wanted to do a CT (wild goose chase, essentially) and I declined because of not being able to nurse for 48hrs. The doctor wasn't happy with me. A nice male nurse on the next shift woke me up with printed out papers (he searched online) from studies (I think from the American College of Radiology) showing that it was okay. It named a few different drugs, I think the one you listed was one of them.
