virtual colonoscopy

n.
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.

virtual colonoscopy

an imaging technique, used for examination of the colon, in which cross-sectional images acquired by computed tomography or magnetic resonance imaging are processed by computer to reconstruct a three-dimensional display of the colonic lumen.
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.
