title: Stone disease.
abstract: Imaging studies used for the detection and characterization of urinary tract calculi are presented in this article. Comparisons of traditional imaging studies are made with noncontrast helical CT scanning, the most recent addition to stone imaging. Imaging findings for noncontrast helical CT and an approach to dealing with various combinations of CT studies are also presented.
