What is this test?

A CT scan of the elbow uses x-rays from multiple angles to create detailed pictures of the joint, bones, and nearby soft tissues. Intravenous contrast, usually an iodine-based liquid, may be injected through a vein to improve the visibility of certain tissues.

Why might I need this test?

This test may be ordered to evaluate persistent elbow pain, swelling, injury, or difficulty moving the joint. It can show complex fractures, bone alignment problems, arthritis, fluid collections, or other abnormalities.

How is the test performed?

You will lie still on a padded table while the CT scanner takes x-ray images. If contrast is needed, a technician may inject it into a vein in your arm; you may briefly feel warmth or a flushing sensation.

How do I prepare for the test?

Follow your appointment instructions, and do not eat or drink beforehand unless the imaging center tells you to. Tell the care team about any previous reaction to IV contrast, kidney disease, pregnancy, or breastfeeding, and bring relevant medical information.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Abnormal findings may include a fracture, dislocation, misalignment, arthritis, tendon or ligament injury, fluid collection, infection, or a mass. The images must be interpreted by a radiologist together with your symptoms, physical examination, and other tests. A normal CT scan does not rule out every minor tendon, ligament, or cartilage problem.

Frequently asked questions

Does an elbow CT scan use radiation?
Yes. CT scans use x-ray radiation, but the scan itself is generally quick and painless.
Why is IV contrast used?
IV contrast can make blood vessels and certain tissues easier to see on the images. It may also help identify inflammation, infection, bleeding, or a mass.
Is an elbow CT different from a regular x-ray?
A CT scan provides cross-sectional images and may reveal more complex fractures or surrounding soft-tissue abnormalities. A radiologist will determine which imaging study is most appropriate based on the clinical concern.
