What is this test?

A sternum CT scan uses X-rays and computer technology to create detailed images of the breastbone, or sternum. Intravenous contrast may be given through a vein to improve the visibility of certain tissues and blood vessels.

Why might I need this test?

This test may be ordered to evaluate breastbone pain, a suspected fracture, an abnormal bone shape, or other structural changes. It may also help assess nearby soft tissues or the cause of pain when standard X-rays are not sufficient.

How is the test performed?

You will lie on a CT table while the scanner rotates around you and takes X-ray images. If contrast is required, a clinician will usually inject it through a vein in your arm; the scan is generally painless and takes a relatively short time.

How do I prepare for the test?

Follow the instructions provided by the imaging center, including whether you should avoid eating or drinking beforehand. Tell the care team if you are pregnant or may be pregnant, have kidney problems, or have previously reacted to iodine-based contrast.

Frequently asked questions

Is a CT scan of the sternum the same as a chest CT?
No. A sternum CT focuses specifically on the breastbone and nearby structures, although some images may include a limited portion of the chest.
Does the test use radiation?
Yes. CT scans use a small amount of ionizing radiation, and the benefit is generally considered when detailed images are needed to guide diagnosis or treatment.
Will I need intravenous contrast?
The test name indicates that contrast may be used. The imaging center will explain the specific preparation required and confirm whether you can receive contrast safely.
