485 patients,who have an average risk (asymptomatic and without colon screening in the last 5 years) or those who have a high risk for colon cancer (strong family history of colon cancer or polyps and/or personal history of colon cancer or polyps).
160 patients, with a known colorectal lesion at or greater than 1 cm.
610 patients, who are of average risk for colon cancer (asymptomatic and no colon cancer screening in the last 5 years).
- To optimize diagnostic performance of CTC in the unprepared colon for colorectal polyp detection using electronic stool subtraction and computer-aided diagnostic techniques. [ Time Frame: 2000-2009 ]
- The cost-effectiveness ratio of CTC in the unprepared colon will compare favorably with other colorectal screening tests [ Time Frame: 2000-2009 ]
