U.S. Food and Drug Administration (FDA): Computed Tomography (CT)

Computed Tomography refers to a medical imaging technique that produces detailed cross-sectional images of various body parts. It utilizes specialized X-ray equipment that processes an array of X-ray images taken from multiple angles around the body and creates detailed images studied by the clinicians. Computed tomography (CT) is an essential medical tool that helps clinicians evaluate conditions to diagnose diseases, detect internal injuries, and plan surgical, medical, or radiation treatment. CT angiogram is a test that provides detailed pictures of different body parts via X-rays. It helps observe the blood vessels that go to the heart, lungs, and neck arms and help diagnose narrowed or blocked blood vessels. One example of computed tomography is a CT scan head that employs X-ray to take pictures of the brain, skull, and other areas to diagnose abnormalities.
