I happen to think that "perspicacious" is the perfect descriptor of radiologists (but then again, I am biased!).
Just like the famous detective, radiologists are tasked with solving complex problems, picking up clues from imaging tests and putting together seemingly unrelated pieces of data to synthesise a unifying diagnosis. Observation skills and lateral thinking are key weapons in the radiologist's armoury, and being able to gaze through the mist of information and noise to identify a key single finding is what makes radiologists perspicacious.
So the next time I'm asked to use a word to describe myself, I think I'll use perspicacious!
