This is my first post on this forum, so please forgive me if I offend.
I guess this falls into the "other resources" category:
I'm an X-Ray tech, and I've shot and looked at a bazillion CXRs. One of my jobs is at an Urgent Care that is located about 5 miles from a medical school, and (with my doc's permission of course) I invite med students to look at various x-rays all the time. That facility has digital x-rays, so I can sort them by study type and by who took them (usually me, so I have an idea what the diagnosis turned out to be). A few clicks more and we look at the over-read sent back by the radiologist.
Once a week or so, my doc and I spend half an hour with two or three med students looking at real world studies on the gear you'll be using when you get into practice. I hope all those med students remember me when I apply to go to their school in two years...
Radiology is all about pattern recognition. Learn a few different ways to look (ABCDE, etc.), then find a kindly tech or a doc who will show you a bunch of studies. The more studies you see, the more the anomalies seem to jump out at you. It's also helpful to have access to the chart or someone who laid hands on the patient, so you get an idea of what the chief complaint/H and P translates to on film. I liken it to learning a language - daunting at first, but as your brain builds a vocabulary for radiographic interpretation, it makes more and more sense.
Not all of us allied health people are bad folks - in many cases, you'll find people who have their eye set on med school (like myself), or realize that we'll be working for you in a few years anyway and we might as well build a positive relationship now. Ask around - I'll bet you'll get some scope dope like me to help you. Just be personable and respectful, and somebody like me will be happy to give you a hand.
