I also am a radiologist and during my residency when you were on the fluoscopy rotation (upper GI series, barium enemas, etc) you were the Barium Boy and the staff radiologist was Captain Fluoro. Sort of a really twisted crime fighting team. Well, I'm no longer in my residency and although I am in private practice with no Barium Boys I now consider myself Captain Fluoro. Just remember: Barium cures all.
