A noninvasive, advanced CT scan that produces two- and three-dimensional images of the colon and rectum. The entire colon must be cleaned out for this procedure, just like a traditional colonoscopy. If abnormalities are found, your doctor will talk to you about the appropriate diagnostic procedure moving forward. Not everyone is a candidate for CT colonography, so be sure to talk to your doctor about this colorectal cancer screening option.
- Should be covered by insurance, but discuss with your insurance provider before undergoing this screening exam.
- Requires bowel prep.
- Repeat every 5 years, if normal.
- Takes place at a hospital, clinic, or outpatient imaging center.
- If any abnormalities are found, a follow-up colonoscopy is required.
May be a good option for people who aren’t eligible or cannot tolerate a traditional colonoscopy.
