Why would that be crazy? Makes perfect sense to me

What led you to this point?
Happy to answer!
Rads was the last specialty I ticked off my list as a 4th year. It seemed like a great fit for my strengths and personality, but I felt I couldn't let go of the potential to operate (it's why I applied to medical school!). I'm a medicine prelim now (this may tattle on my specialty), and I've found I can be perfectly content without the OR. While there is plenty I don't like about my work on the wards, being involved in the full spectrum of human disease has been really engaging. I have even enjoyed ICU the most after hating it in medical school!
After 2 months on my subspecialty service I missed the full breadth of medicine and found it unfulfilling in a way I didn't expect. My wife even commented on how much happier I seemed on my medicine time. I missed the problem solving. Although I still enjoyed how visual it was, I was counting down the days until I got back to medicine. I also found myself most engaged with the diagnostic and cognitive aspects of medicine over the past 6 months. And across all of it I still found the patient interactions in clinic and the wards completely exhausting. My faculty reviews so far as an intern commend my people skills, but I have come to dread a lot of the face to face patient time, which I feel is also incompatible with the busy clinics in my specialty of choice. All the above (and more but I don't want to bore anybody!) brought me back to the bottom of my original decision tree, to radiology.
In summary, the rigor of intern year gave me a lot of clarity about what I want (broad medical knowledge base, minimal patient contact, lots of thinking, working with other physicians, heavy visual component to my work) and what I don't want (OR, busy clinics, contained knowledge of one region of the body).
