What do radiologists look at?

[brockenspectre]

I have been having a debate with a couple of friends about what it is radiologists look at and I am hoping that someone here can clarify for me!

If you have your abdomen scanned because your doctor (of any specialty that manages the trunk) has requested it, does the radiologist only report on those issues they see pertaining to the target, or do they review everything that has been caught in the scan?

Both my friends say that the radiologist will only report on the matter they have been asked to investigate (ie, bowel, liver etc), whereas my view is that while the target area is the prime mover for the scan in question, a radiologist will review the slides/films and report on anything seen that isn't what it should be irrespective of where it is.

Can someone here tell me what is correct please? and does this vary depending on what country you are in?

Thanks in advance for any/all replies
