CT Scan (used to see internal structures)

What is a CT scan?

A CT scan stands for Computed Tomography scan. It is also known as a CAT (Computer Axial Tomography) scan. A CT scan combines a series of X-ray views taken from many different angles to produce cross-sectional images of the bones and soft tissues inside your body. CT images provide more detailed information than normal X-ray images. A CT scan can be used to visualize nearly all parts of the body.

Preparing for a CT Scan

  • You may be asked to fast (not eat) for 4 hours prior to the exam.
  • In some cases, you may be asked to drink up to 1000 mL (4 cups) of water before the exam.
  • You may be asked to drink a contrast agent the night before the test.
  • If you are having a CT colonography exam, you will be required to follow a detailed bowel preparation. Instructions will be given to you before your scheduled appointment.
  • You may require routine blood work prior to your CT scan.
  • Please inform your primary care provider and technologist if you are or might be pregnant.

Risks or Complications:

Minimal exposure to radiation

Although rare, the intravenous (IV) contrast material involved in some CT scans may cause medical problems or allergic reactions in some people. Most reactions are mild and result in hives or itchiness. In rare instances, an allergic reaction can be serious. Make sure to tell your primary care provider if you have had a prior reaction to contrast material (X-ray dye) during medical tests.

How long will a CT scan take?

The scan can take from 10 to 30 minutes, depending on the type of test being done.

After Your Procedure

  • You can return to your normal routine.
  • If you were given a contrast material (X-ray dye), your primary care provider, a nurse or the CT technologist performing the scan may give you special instructions.
  • You may be asked to wait for a short time in the Radiology Department to ensure that you feel well after the exam.
