Guidance on the use of CT colonography for suspected colorectal cancer

Date: 2014

The number of CT colonography examinations is increasing in the UK for suspected colon cancer, having now replaced the barium enema as the alternative imaging investigation of choice when colonoscopy is incomplete or the patient is considered unsuitable for colonoscopy. The British Society of Gastrointestinal and Abdominal Radiology (BSGAR) and The Royal College of Radiologists have produced this document to set out the key considerations in using CT colonography for suspected colorectal cancer as well as important guidance on all aspects of establishing a high-quality CT colonography service.

However, there are hurdles in instituting a change in UK practice from BE to CTC, not least that a BE service is largely delivered by radiographers, while CTC places additional pressure on CT workload and consultant reporting time. The purpose of this guidance is to set out some of the key considerations in the use of CTC for suspected colorectal cancer.

This document was reviewed by the Clinical Radiology Professional Support and Standards Board and the Clinical Radiology Faculty Board in 2017 and was retained in its current format.
