Zero to 64: CT urography zooms ahead with more detector rows

That more image details would be visible with additional CT detectors seems logical enough. But real-world examples have been sparse, and clinical studies comparing four scanner generations side by side are rare birds indeed. But two groups, from Boston and the Mayo Clinic, have focused their research on comparing generations of multidetector-row CT systems using a CT urography protocol.
