Cost-Effectiveness of CT Colonography [PDF]

Radiologic Clinics of North America, 2013
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.
