What are the advantages of CT colonography?

  1. Less invasive—better patient acceptance. No six foot scope advanced to the cecum, which translates to better patient acceptance.
  2. Safer: The Perforation rate 10-20x lower than colonoscopy for a diagnostic, lower for therapeutic
  3. Very short procedural time. Scan in two positions: supine (lying on the back) and prone (lying on the front) that takes less than 10 seconds
  4. No need for sedation which is necessary for both colonoscopy and sigmoidoscopy (looking inside the sigmoid colon and rectum).
  5. Less costly than colonoscopy
  6. Extracolonic evaluation- Affords ability to evaluation structure outside of the colon
  7. Not enough gastroenterologists to perform all the colonoscopy in our aging population.
