CTC examination with automated quantification of residual colonic fluid volume and attenuation in a 57-year-old man. (A) Three-dimensional display map of the correctly segmented colon. The automated volumetric CTC tool allows accurate quantification of the amount and attenuation of the total residual colonic fluid. Automatically calculated total colonic residual fluid in this patient receiving novel OSS regimen was 73 ml. The automatically calculated attenuation of the residual fluid was 826 HU. Two-dimensional axial CTC images before (B) and after (C) automated digital subtraction of residual colonic fluid allow verification of correct segmentation. Note that not only large fluid collections (arrow) are captured but also smallest fluid residues (arrowheads).
