CT Scan of the Chest (Thorax)

UPMC Content 2

About this Exam

A computed tomography (CT) scan is a special computerized x-ray test that allows your doctor to see your organs, bones and tissues. This test is done to help diagnose various disease processes in the chest. Your doctor or radiologist, if appropriate, may request that you receive contrast through a vein in your arm to aid in that diagnosis.

  • If you will not be receiving intravenous contrast, no prep is required. Please skip to "Day of Exam."
  • If your doctor or radiologist wants you to have intravenous contrast, please follow the instructions in the next section.
