Medical imaging is not about getting the expected result as is typical in most bodies, rather, it is about getting the actual result as is found in this body.
Similar to blood work maybe nothing comes back conclusive but it might be interesting enough to trigger follow on investigation.
But the general theme is around augmenting the human decision maker rather than "preprocessing" the data in a way that might obscure or hallucinate important details.
I’m more interested in AIs ability to do things like read x-rays and identify illnesses with higher accuracy than a tired doctor on a 12 hour shift.
Sure, there are many applications and more coming. In your example of an actual result as is found in this body, the image segmentation [0] and recognition task is applicable.
One of the bullet points in the above is "Intra-surgery navigation." Let's say there is a known position of a tumor within an organ based on previous imaging. The human body is squishy and interior organs may shift in position or shape when a procedure is performed. Deformable image registration [1] guides the surgeon (human or robot) to the tumor location with greater precision than what was possible before.
