CT Colonoscopy: A Recommended Screening Option

On May 30, 2018, the American Cancer Society updated its colorectal cancer screening guidelines for people at average risk. The new ACS recommendation states that people of average risk for colorectal cancer should begin regular screenings at age 45, instead of starting at age 50 as recommended in the previous guidelines.

People in good health and with a life expectancy of more than 10 years should continue regular colorectal cancer screening through the age of 75. For people ages 76 through 85, the decision to be screened should be based on overall health, prior screening history, and life expectancy.

The previous guidelines recommended some screening tests over others, but the new guideline does not, although the double-contrast barium enema is no longer included as an acceptable screening option.

CT colonography (virtual colonoscopy) is one of the recommended screening exams, to be repeated every five years. Virtual colonoscopy is a minimally invasive procedure to detect polyps and cancers in their early stage. Colon cancer can almost always be cured if detected early. Advantages for virtual colonoscopy include:

  • Immediate return to all normal activities following exam
  • Increased comfort since only a small amount of air is introduced into the colon
  • Shorter exam time (approximately 10 minutes) due to high-speed CT

Lake Medical Imaging’s board-certified radiologists perform CT virtual colonoscopy at our Leesburg location, in addition to the Sharon Morse Medical Center location in The Villages.
