title: Cost-effectiveness of CT colonography.
abstract: Simulation modeling is extensively applied to CT colonography (CTC) to define its long-term efficacy and cost-effectiveness for colorectal cancer (CRC) screening. CTC is effective in reducing CRC incidence and mortality (40%-77% and 58%-84%, respectively). Several factors may explain this variability. CTC is cost-effective compared with no screening, indicating that it represents an attractive test noncompliance with the available options. CTC needs to achieve a higher attendance rate or cost less than colonoscopy to be cost-effective relative to colonoscopy. Fortunately, both conditions appear to be achievable if CTC becomes a widely utilized and reimbursed screening tool.
