The purpose of this study was to evaluate the effect of use of dual-energy CT monochromatic imaging in the late hepatic arterial phase on hyperenhancing focal lesion detection and lesion conspicuity. This prospective study included 72 patients imaged with a single-source dual-energy CT scanner. Late...
