Although optical colonoscopy has been shown to be effective in detecting colorectal cancer and thereby prevent deaths, a large percentage of patients are unwilling or unable to undergo the procedure. Virtual colonoscopy provides a safe, effective alternative to screen for colorectal cancer that clinicians can use to improve compliance, and hopefully save more lives in patients that have an average-risk of colorectal cancer and do not have symptoms of colorectal cancer.
