Comparison of Radiation Exposure in Third-Generation Second-Generation Dual-Source Dual-Energy CT for Imaging Urinary Calculi.

To investigate the potential for decreasing radiation dose when utilizing a third-generation second-generation dual-source dual-energy CT (dsDECT) scanner, while maintaining diagnostic image quality and acceptable image noise. : Retrospective analysis of patients who underwent dsDECT for clinical suspicion of urolithiasis from October 2, 2017, to September 5, 2018. Patient demographics, body mass index, abdominal diameter, scanning parameters, and CT dose index volume (CTDIvol) were recorded.
