My opinion as a rads resident:
Look at where the two specialties work. Pathologists work in odd-smelling labs, and often have to go do gross dissections of surgical path.
Radiologists have comfortable chairs in an office-building type room, with coffee and snacks nearby.
The working environment is very different, and that matters!
Pathology is seeing a decrease in number of US grad applicants. This post explains why. Medical students, residents and Attendings don’t even know what we do and our lifestyle. Sad for our field!
