The author reflects on the use of computed tomographic (CT) colonography in the diagnosis of colorectal cancer (CRC). In his view, CT colonography is an emerging diagnostic test that has the potential to provide another effective CRC screening option, which would surely be beneficial in reducing the high number of people with CRC. However, he pointed out that to achieve any real benefit, a new test must succeed in attracting additional patients to undergo screening.
