To simplify the procedure and to reduce the number of phases necessary, a split bolus technique of contrast administration is used, resulting in scanning during a simultaneous nephrographic and excretory phase.Nephrographic and excretory phase images have previously been shown to be superior to corticomedullary phase images in the detection and characterization of renal masses.
