What are the advantages of CT colonography?
- Less invasive—better patient acceptance. No six foot scope advanced to the cecum, which translates to better patient acceptance.
- Safer: The Perforation rate 10-20x lower than colonoscopy for a diagnostic, lower for therapeutic
- 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
- No need for sedation which is necessary for both colonoscopy and sigmoidoscopy (looking inside the sigmoid colon and rectum).
- Less costly than colonoscopy
- Extracolonic evaluation- Affords ability to evaluation structure outside of the colon
- Not enough gastroenterologists to perform all the colonoscopy in our aging population.
