It's not so much the lack of interaction with the patients.
When I was in Path, I found it interesting, for a week or two, but then I began getting really antsy. I couldn't handle being behind the microscope, constantly looking at slides and trying to detect anomolies, the slow pace, being confined to the limited space of the path lab, etc.
I see some of these same qualities in Radiology and I wonder if I would get antsy in the reading room as well. What do you think?
