The article presents information on the use of virtual colonoscopy for colon cancer screening. In virtual colonoscopy, an abdominal computerized tomography scan is rendered into a 3-dimensional image that looks like the image from conventional colonoscopy. A laxative preparation, understandably unpopular with patients, has been needed for conventional colonoscopy and, until now, for virtual colonoscopy. Radiation dose, expense and inconvenience may be important factors inhibiting the adoption of virtual colonoscopy screening.

    Narrow-band imaging (NBI) is a new imaging technology that was developed in 2006 and has since spread worldwide. Because of its convenience, NBI has been replacing the role of chromoendoscopy. Here we review the efficacy of NBI with/without magnification for detection, characterization, and...
