Abstract: Background: Computed tomographic colonography (CTC) is a minimally invasive imaging method for the detection of colorectal neoplasms. Uncertainty about its diagnostic performance, optimal visualization method, long learning curve and radiation exposure are among problems with CTC, affecting its implementation in routine health care. Potential means of improvements include novel three-dimensional (3D) CTC displays, such as “Perspective-filet view” (3D Filet), and computer-aided detection (CAD). I... more
