What exactly is quality in radiology?
June 25, 2015 -- In the ever-evolving healthcare delivery environment, the discussion is centering on the need to shift from volume to quality. But what does the word "quality" actually mean in the context of radiology? It's imperative that radiologists work to define it, according to a talk at the recent International Symposium on Multidetector-Row CT.
