This session has four sections. First is CT Colonography: Technical Considerations, which performs CT colonography studies. The section discusses key elements to CTC quality assurance, in addition to employing techniques to optimize CTC in difficult cases. The second section is CT Colonography: Interpretation, Reporting, and Pitfalls, which highlights the differences between lesion detection (primarily at 3D) and lesion characterization (primarily at 2D) at CTC. It also discusses key elements of a CTC clinical report, with emphasis on structured reporting, and common interpretive pitfalls at CTC. The third section is CT Colonography: Summary of Data—Controversies and Policy Update, in which attendees will understand the performance characteristics of CT colonography as reported in recent national and international CT colonography studies. The section reviews recent articles investigating the impact of extra-colonic findings in screening CTC and implications for impact on cost-effectiveness. It also reviews the new American Cancer Society and USMSTF guidelines for colorectal cancer screening and surveillance. The section highlights the efforts at establishing national benchmarks for CTC, efforts to extend colorectal cancer screening using CTC, and explore emerging trends in minimal cathartic CTC. The fourth section is Colorectal Cancer: Diagnosis and Staging, which discusses the staging of colon-rectum cancer and treatment strategies based on TNM staging. The section highlights the role of various imaging modalities CT/MR/PET-CT in the evaluation of CRC. It also lists a number of MR Imaging techniques for facilitating T-staging. Attendees will study the existing and emerging imaging methods for monitoring treatment effects.
