Computed tomography (CT) is a diagnostic procedure that uses special X-ray equipment to create cross-sectional pictures of a person's body. CT images are produced using X-ray technology and powerful computers.

The uses of CT include looking for:

  • Broken bones
  • Cancers
  • Blood clots
  • Signs of heart disease
  • Internal bleeding

During a CT scan, the patient lies still on a table. The table slowly passes through the center of a large X-ray machine. The test is painless. During some tests, the patient receives a contrast dye, which makes parts of their body show up better in the image.[1]
