RESUMO
Virtual colonoscopy represents a noninvasive test for the examination of the colonic lumen that involves the generation of both 2-dimensional and 3-dimensional views of the colon and rectum using data derived from computed tomography. This imaging modality has been explored as an alternative to conventional endoscopic colonoscopy, in particular as an alternative screening tool for colorectal cancer. Although virtual colonoscopy does not require sedation and requires less time for completion, the study requires the same bowel-cleansing preparation as conventional colonoscopy as well as gas insufflation of the intestine, which may be associated with patient discomfort.
