Computed Tomography

Computed Tomography or CT Scan, also computerized axial tomography (CAT Scan). A CT Scan uses a series of x-ray images taken from varying angles to generate cross-sectional (tomographic) images – or “slices” – of the inside of the body including blood vessels, organs, soft tissue and bones. A CT Scan produces a more detailed image than a regular plain x-ray, but one is exposed to a greater amount of radiation during a CT Scan than during a plain x-ray.

For health check purposes a CT Scan may be used to screen for conditions or diseases including cancer, nodules on the lungs, heart disease and liver masses. A low dose CT (LDCT) scan of the chest is sometimes used as a screen for lung cancer in those considered at higher risk of developing this form of the disease. The U.S. Preventive Services Task Force recommends LDCT screening for those with a history of heavy smoking, and who currently smoke or have quit within the past 15 years, and are between 55 and 80 years old.
