CT Scans

Also called: CAT scan 


Computed tomography (CT) is a type of imaging. It uses special x-ray equipment to make cross-sectional pictures of your body.

Doctors use CT scans to look for

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

During a CT scan, you lie still on a table. The table slowly passes through the center of a large X-ray machine. The test is painless. During some tests you receive a contrast dye, which makes parts of your body show up better in the image.
