Abstract

Attention is focusing on testing and developing computer aided detection (CAD) systems to reliably highlight flat polyps and cancers to the reporting radiologist during CT colonography. This review will discuss the clinical relevance of flat colonic neoplasia, describe some of the challenges facing CAD detection algorithms, and review the current CAD literature on this topic.
