virtual colonoscopy

A screening examination of the colon in which x-rays obtained by CAT scan are used to generate computerized three-dimensional images of the colonic mucosa.

A diagnostic procedure in which 2-dimensional helical CT images are converted into 3-dimensional images of the colonic mucosa similar to those obtained by conventional colonoscopy.
