Instrument Variable Name: CTHEARD
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.
Before today, HAD YOU EVER HEARD of CT colonography or virtual colonoscopy?
*Read if necessary:
This is not the same as a colonoscopy or a sigmoidoscopy.
Unlike CT tests for other purposes, you DO take laxatives to clean out your colon for this test.
