1) To review current imaging technology and its limitations in CT urography 2) To illustrate novel imaging technologies for reducing radiation exposure and contrast medium load in CT urography 3) To learn optimal strategies using these current and novel technologies by presenting experimental data and clinical images  

1) Standard imaging technology and its limitations ・ single-bolus triple phases (unenhanced, nephrographic and excretory phase) ・ image quality ・ radiation exposure ・ contrast medium (CM) 2) Current and novel imaging technologies ・ split-bolus double phases (unenhanced, nephrographic- excretory phase) ・ low kVp technique ・ low CM dose and concentration ・ iterative reconstruction (IR) ・ dual-energy CT (DECT): virtrual unenhanced scan/monochromatic imaging/material density imaging 3) Optimal strategies using these technologies
