Many of the challenges with radiology are historical. Imaging technologies have been treated as a devices for producing images on which measurements can be made, rather than a measurement device from which images are formed. This has lead to difficulties for quantitative imaging techniques and so we continue to rely on the (albeit impressive) qualitative assessment of the radiologist. This is changing (shameless plug for my company http://www.pulmolux.co.uk http://www.pulmolux.co.uk) but medicine moves slowly preferring evolution over revolution. Having said that, I certainly detect that the scanner manufacturers (GE, Philips, Siemens, etc) having reached saturation with radiologists now have a thirst for disruption and see the referring physician as the next customer. MRI cardiology being something of an example.
