FERNANDEZ A, Manuel  e  ALDANA V, Hernán. COLONOSCOPIA VIRTUAL. Rev. chil. radiol. [online]. 2006, vol.12, n.2, pp.64-69. ISSN 0717-9308.  http://dx.doi.org/10.4067/S0717-93082006000200005.

Since the first report in 1994 virtual colonoscopy or CT colonography has had an explosive development due to the improvement in hardware and software. The multidetector CT has allowed faster studies with better images due to better multiplanar reconstructions and its speed avoiding the artifact of the breathing or bowel peristalsis. The new software has allowed to obtain better 3D images and faster reconstruction with shorter interpretation. This development, the use of standarized protocol plus the experience of trained radiologists have obtained sensitivity and specificity over 85% and 95% in polyps smaller and larger than 10 mm respectively. These results and the lower price of virtual colonoscopy in the United States compared with fibrocolonoscopy has done this technique a real alternative for the screening of colorectal cancer side by side with fibrocolonoscopy
