To all medical students out there: Be careful making assumptions and forming stereotypes about radiology/radiologists based upon what you see at your school's hospital.
By definition, your first hand experience of these things is with academic radiology. In reality, 95+ % of radiologists work in the private practice sector.
There is a huge difference in private practice radiology and academic radiology in so many ways...one of which is personality. In general, academic radiologists are a different breed than their private practice counterparts. On average, they tend to be less sociable and personable.
I would encourage everyone interested, or who thinks they might have an interest in radiology to spend some time in the private practice setting. As a third year medical student, I had an interest in radiology and thought it might be something that would fit me well. After doing a two week rotation my third year, I was disappointed with what I saw because frankly I didn't like it very much at all and was upset because I thought it was something I would really want to do. The first month of my fourth year, I was able to do an "away" elective through my school with a private practice group in town and ended up loving it.
The difference in my experiences was enormous. Some of that difference had to do with the people. The private practice guys were fun people. They cracked jokes all the time while working around each other, would talk about the football game that was on the night before, and had absolutely no desire to discuss the latest cutting edge research in MR magnets. This was in stark contrast to the academic side of things, where the people tended to isolate themselves in their work, didn't even know who played in the game the night before, and when they did get together would love to discuss all the latest updates in radiology that they knew of.
There are so many more differences in private practice than academics than just the personalities though. It's hard to appreciate the them unless you experience them first hand. Some people like the academic side of things more. However, the reality is that the greater majority of us will end up in private practice. If that's the case, then you should probably make an effort to try and check out what the typical day is like for a private practice guy instead of just basing your opinions and decisions or radiology on your academic experience.
