Isn't that 90% of going to get scan is right now? You'll still need the "shop" to provide the equipment and the tech with the training to know what/where to scan, but you might get the results a bit faster? Are the radiologists the chokepoint now, or is it the techs?

That's the way it already works in many cases, just like with outpatient surgery clinics and other outpatient specialist practices. There is a critical difference, though, because radiology also has sub-specialities and someone focused on orthopedics probably isn't the one you'd want reading your cardiology images, nor would you want your ophthalmologic radiologist trying to diagnose a brain CT.
