CT Colonography

This CT Colonography section provides links to useful information to support the planning and delivery of a high quality CT Colonography service.

The section is currently under development and additional information will be added when available.

Background

CT Colonography has gained widespread acceptance as the investigation of choice when radiological imaging of the whole colon is required for suspected colorectal cancer, and should replace the Barium Enema. It is safe, accurate and better tolerated by the patient compared with Barium Enema (BE), the traditional radiological means of imaging the large bowel. The prospective, multicentre, randomised SIGGAR trials, published in February 2013, have shown that CTC is significantly more sensitive for detecting cancers and large polyps than BE, whereas there is no significant difference in detection rates between CTC and colonoscopy.

There are significant cost, training and workforce implications in delivering a CTC service, as well as a commitment to quality assurance in maintaining and improving CTC performance and outcomes. The subsections provide some of the information to support the planning and delivery of a high quality CT Colonography service
