"CTC of the Unprepped Colon: Optimization & Validation"
To improve the diagnostic performance of CTC in the prepared colon using improved spatial
resolution, advanced image displays, and computer-assisted diagnosis, and to optimize
diagnostic performance of CTC in the unprepared colon for colorectal polyp detection using
electronic stool subtraction and computer-aided diagnostic techniques. To estimate the
sensitivity and specificity of CTC in the unprepared colon for clinically important
colorectal neoplasms (large adenomas ≥ 1 cm) and to compare such estimates with colonoscopy.
To survey patient acceptance of CTC in the unprepared colon, and to assess implications
for health care costs and cost-effectiveness of CTC in the unprepared colon in comparison
with other approaches.
