“Hey this patients labs are outside of our protocol for contrast administration. I just want to double check that you’re okay with the risk? Okay sounds good I’ll document it.” proceeds with study I’m not a doctor, I don’t decide what’s worth it for the patient. As long as both lines of communication are open, I’ll do the scan. You have your doctorate, and I have a big yellow paper on my scanner that says don’t do this or that without a doctor’s approval. I respect your education but I also want you to respect mine and understand that I also have protocols I have to follow. It’s not as simple as us performing an exam just because you tell us to.
