Whoever decided that axial images are viewed from below fumbled bigtime.
Don't we all think of anatomy in terms of it on ourselves, looking down from above? My liver is on the right side of my mental image of a cross section at that level; my spleen is on the left.
I don't have the same issue with coronal images or plain films - the right/left swap is intuitive and on autopilot, because we have spent all our lives seeing people from the front.
Nothing else in life gets rendered from below. Nobody draws a map of a building from below. Nobody draws a map of a mountain from below. Every other cross section in daily life is viewed from above.
"It's because you examine the patient from the end of the bed", they say. Maybe if you're a podiatrist. But all the important organs are in the upper half of the body and that's where you're standing when you examine.
Whoever came up with the inferior view convention was having a laugh; scheming to prank future doctors like myself into wasting 3 seconds on every single CT abdomen looking for an appendix in the left side, before my brain remembers they screwed up.
A prank to catch the eye of passing-by-colleagues, amazed that I have a situs inversus patient, when it was really just a frustrated click of the PACS mirror button.
This would be my priority if I had a time machine.
