I will bite here but I hope it is for your genuine interest and not to help your personal statement.
I chose it for a number of reasons:
- I like to be efficient and work at a fast pace. Rounding for hours on end took me as close to suicide as I have ever been... Someone either said this to me in person or maybe even on this forum. If you get some terrible scan with a ton of pathology and comparison studies it may totally suck for 30 minutes or a little longer. If you are an Internist or other clinician you can have a patient stay with you for months, ouch.
- Radiology provides the opportunity to build a huge medical knoledge base bridging all specialties. You have to know female reproductive pathology, brain tumors, pediatric developmental disorders, etc. This appeals to me and will keep me learning for a very long time.
- In general Radiologists are quite happy. I have yet to meet one who said they wished they did something else. That carried a lot of weight as many surgeons and internists were not as happy.
- The specialty is constantly changing and is improving healthcare rapidly. Faster scanners with better resolution, new IR procedures (chemo-embo, cryo, etc.), and many other things that I have not learned yet.
There are more reasons but that should give you enough to think about.
