What is Virtual Colonoscopy/CT Colonography (CTC)?
CTC is a revolutionary and technologically-advanced new screening test for CRC. CTC is an imaging test that is performed by an advanced CT scanner. Images of the patient’s abdomen are taken by the CT scanner. With special software, these images are put together to create a three-dimensional image of the colon. This 3-D image of the colon provides the same view of the inside of the colon that is seen by traditional colonoscopy. In fact, the views provided by CTC, in many ways, are even better than those seen by traditional colonoscopy.
