CT Scan

Heart Institute at Children’s Hospital of Pittsburgh of UPMC

In conventional x-rays, a beam of energy is aimed at the body part being studied. A plate behind the body part captures the variations of the energy beam after it passes through skin, bone, muscle, and other tissue. While much information can be obtained from a regular x-ray, specific detail about internal organs and other structures is not available.

Computed tomography scans (also called CT or CAT scans) move the x-ray beam in a circle around the body, providing many different views and much greater detail of the same organ or structure. The x-ray information is sent to a computer which interprets the x-ray data and displays it in two-dimensional form on a monitor.

CT scans may be done with or without contrast. "Contrast" refers to a substance taken by mouth or injected into an intravenous (IV) line that causes the particular organ or tissue being studied to be seen more clearly.

Depending on the results of the CT scan, additional tests or procedures may be scheduled to gather further diagnostic information.
