This. 1000 times this. It's not even about automated diagnosis. The software used by most radiologists is more than two decades behind the state of the art, lacking even basic image registration and segmentation capabilities. (source: I've worked with radiologists who review brain images at several tier-one, top-10 hospitals).

If you are lucky, some eager, tech-savvy resident will use 3D Slicer or OsiriX on their personal laptop to coregister and segment images, and do longitudinal volumetric comparison. But those basic tools are not available on the platforms used to read most images.

Major vendors are trying to catch up, but from what I've seen, demand (and thus willingness to invest) is surprisingly limited.
