That paper is a good example actually. The first clinically approved, commercially available breast screening CADe system using NN models was available in the 90s. It too was aimed at the 2nd reader problem. At the time there was a lot of concern radiology circles that algorithms were going to take over. That pretty quickly died down as people worked with CADe and CAD systems. Breast is one of the obvious targets, as data availability is pretty good. So over 25 years there have been incremental improvements, sure, but no real eye opening jumps, The move to deep models has helped a bit but nothing revolutionary. You still find very influential radiologists who aren’t convinced it’s worth the time, yet. I think all of them expect it to be a growing part of the workflows over time but that’s about it. Personally I think the impact will both be much bigger than the pessimistic radiologists think, and much further off than the optimistic ML think (for both non technical and technical reasons). I suspect the broader availability of good digital data has had far more impact than the modeling updates. Don’t get me wrong, I appreciate the tools and modeling developed over the last decade - but I think the big wins are far more about data, and secondarily compute availability than about models.
