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.
