What is this test?

An upper-extremity CT scan uses X-rays and a computer to create detailed pictures of the area being examined. The exact body part may be the shoulder, arm, elbow, forearm, wrist, or hand.

Why might I need this test?

Your clinician may order this scan to evaluate unexplained pain or swelling, a suspected fracture, infection, inflammation, a bone lesion, or another structural problem. It can also help assess injuries that are difficult to see clearly with standard X-rays.

How is the test performed?

You will lie on a CT table while an X-ray scanner rotates around the affected area. The scan is generally painless and usually takes less than 30 minutes. Because this is a scan without contrast, an IV injection of contrast dye is not normally given.

How do I prepare for the test?

Usually no fasting or medication changes are needed. Remove jewelry, watches, hairpins, and other metal objects near the area being scanned, and tell the technologist if you are pregnant or may be pregnant. Follow any additional instructions provided by your clinician.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Abnormal findings may include a fracture, infection, inflammation, a mass, or another injury involving bone or soft tissue. A radiologist interprets the images in relation to your symptoms and examination, and your clinician explains the results and any recommended follow-up. A normal scan does not exclude every possible cause of pain or swelling.

Frequently asked questions

Does this CT scan use contrast dye?
A scan ordered as “without contrast” generally does not require IV contrast dye. Confirm with the imaging center if you have a history of contrast allergy or kidney disease.
Is an upper-extremity CT scan painful?
The scan itself is usually painless. You may be asked to hold still or keep the injured area in a specific position, and the table may move quickly during imaging.
How soon will the results be available?
A radiologist usually reviews the images and sends a report to your ordering clinician. The timing for you to receive the results varies by the healthcare organization.
