Ask Dr. Z

I was just at the conference in Las Vegas. Outstanding. Great information. You mentioned something related to when you, as a radiologist, could order further tests, and I am asking if you have further guidance regarding this issue. When is a radiologist required to contact the referring physician before performing additional tests? I know you mentioned that if the radiologist was the treating physician, further tests could be performed without an order. Do you have anything is a little more clear? My radiology director is a great guy, but I have discussed this with him and he hasn't been able to clarify it for me. Any further help will be appreciated.
