The Harris "Emergency Radiology" text is one of the classics, but it's dense and expensive. At the same time, that density is full of information. As a reference, it's invaluable, but, for a quick reference, it might not be what you need. Still, the more I look at it, the more I like it. It's always good to have "a chip in the game" - to speak with (some) confidence to the radiologist on why you need the MR right now.
Your department should have a copy (and, if not, your hospital library DEFINITELY should have it). Look at it first, and see if you dig it.
