For me it’s something my father, also a radiologist, taught me decades ago. The human body is a bunch of tubes. Only 1 of 6 bad things can happen to that tube:

1. Innie (polyps/neoplasia)
2. Outies (diverticula, fistula and perforation)
3. Narrowing
4. Dilation
5. Thickening (any itis)
6. Displacement (push or pull like a hernia)

I’ve found beginning residents/students remember pathology much better once they realize they’re looking for one of those six patterns.
What concepts changed the way you read studies?
