The U.K. Clinical Advisory Committee on Diagnostic Imaging has found that CT screening of the colon, heart, and lungs is clinically effective and exposes patients to safe levels of radiation.

The U.K. Clinical Advisory Committee on Diagnostic Imaging has found that CT screening of the colon, heart, and lungs is clinically effective and exposes patients to safe levels of radiation.

The committee reviewed clinical research evidence to assess CT screening's role in preventive medicine. It concluded that CT colonography in experienced hands can detect colon cancer at its earliest, most curable stages; that coronary artery calcium scoring, alone or combined with other factors, is the most powerful risk indicator for coronary artery disease; and that lung cancer screening could reduce mortality by 80% in high-risk patients.

The panel proposed annual outcome audits to maintain published standards and better infrastructure to ensure compliance with international radiation exposure protocols.
