Bottom line: Don't try to look SMART by your radiology knowledge. Try to look MOTIVATED, EASY GOING and PLEASANT. If you want to look SMART try it by your general medicine knowledge at most. There has been many times that a stellar candidate was not ranked in a top program just because other people (residents, fellows and attendings) didn't like him. "Though he is extremely smart, he is NOT THE RIGHT PERSONALITY for our program."
Let me apologize if I failed in my two posts here to convey that the
most important thing is to
be a cool person to be around. Like Shark says, you should be easy going, pleasant, and as fun to talk to as possible. That's rule number #1 and #2 and should be your focus on any away for impressing the program and having a good time yourself.
While I agree with Shark about most posts he has on here, I disagree that you should "not try to look smart by your radiology knowledge".
There's a fine balance between looking smart and coming off as an overbearing gunner. Use your common sense to judge what's appropriate. Obviously, just like every other rotation you have and will be on, never interrupt as the attending is making teaching points, never intervene when a resident doesn't know the answer you know, etc. However, if you're asked a question, which hopefully you'll be asked a lot of questions like I was, it's nice to know a few answers - it's even better to know a lot of answers. Answer respectfully, and be cool about it. It's helpful for a future program to know that you are motivated to learn radiology as well, in my opinion. Having a little knowledge also has the added benefit of making the day
much more interesting since you will know a little bit about what you're looking at.
Regarding Shark's suggestion that you rotate through general radiology to meet as many people as possible, I see his point. It's obviously paramount you meet enough people who can say good things about you to the right people (the program director, assistant pd's, etc.). You can do this easily if you introduce yourself to people at morning and noon conference and behave in a friendly manner. If you have an interest in spending a day in another subspecialty, most programs will accommodate you. However, if you would like to get a strong letter of recommendation from an attending on your away as well, it is invaluable to have worked with them multiple times which you will likely not do if you're merely floating around from place to place. If you're painfully shy, it would likely help you to do a general rotation, like Shark suggests, to meet more people, but there are other ways to accomplish this.
Bottom Line:
#1 Be a cool person to be around.
#2 Did I mention, "be cool"? Seriously, relax and be pleasant to be around.
#3 Introduce yourself to as many people as possible: attendings, residents, program coordinators
#4 Learn some radiology by doing some reading and attempt to gain a little knowledge out of the rotation.
#5 Show this knowledge in a polite manner when questions are directed your way. Never interrupt teaching points or residents.
