View in Spanish: Colonografía tomográfica computarizada

Computed tomographic colonography (kum-PYOO-ted toh-muh-GRA-fik KOH-lun-AH-gruh-fee)
A method to examine the inside of the colon by taking a series of x-rays. A computer is used to make 2-dimensional (2-D) and 3-D pictures of the colon from these x-rays. The pictures can be saved, changed to give better viewing angles, and reviewed after the procedure, even years later. Also called computed tomography colonography, CT colonography, CTC, and virtual colonoscopy.
