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.
