Codes and Frequencies
For sample adults aged 40 and older, CTCOLHEARD reports if the person had previously heard of CT colonography or virtual colonoscopy at the time when the survey was conducted.
The respondents were told that:
"CT colonography, sometimes called virtual colonoscopy, is a new type of test that looks for cancer in the colon. Unlike regular colonoscopies, you do not need medication to make you sleepy during the test. In this new test, your colon is filled with air and you are moved through a donut-shaped X-ray machine as you lie on your back and then your stomach."
