Paul Chang, M.D., is a professor and vice chair of radiology informatics at the University of Chicago School of Medicine. He’s also an entrepreneur, having co-founded picture archiving and communications system vendor Stentor Inc., now Philips PACs after the company was sold to Philips Healthcare. And yes, the check from Philips was really big.

There remains plenty of opportunity for innovation in radiology and the best ideas come from those working in the trenches, Chang says. For instance, traditional vendor offerings don’t address radiologists’ revenue management needs as the specialty moves from fee-for-service to value-based payment models, he contends. Radiology has been a major revenue generator for hospitals, but under accountable care organizations it’s becoming a major cost center in an environment where costs have to fall while outcomes improve at the same time. So there is opportunity to offer new tools in radiology to understand how information moves and reduce overutilization of imaging.
