Objectives

Narrative objectives1

To address the accuracy of CT colonography (CTC) in detecting colorectal polyps and cancers in subjects at increased risk of colorectal cancer, using optical colonoscopy as the reference standard. This clinical study will also evaluate the differences of the detection accuracies between human readings with and without computer-aided detection (CAD). In addition, this study will compare diagnostic performance between radiologists and gastroenterologists.
