I think you should mention it to him there are ways of saying things that it doesn't sound mean but he should know - I mean I'd be grateful that he's saved you life etc... But at the same time there are a lot of element to healing! I agree with Anne Marie - you don have to be mr personality as long as you do you job well but it helps to realize that the patients you're working with are particularly vulgetable and scared - clean scans or not! So a little sensitivity is a good thing. Busy or not when you are with someone they deserve your undivided attention.
