What is this test?

A right upper extremity CT scan uses X-rays and a computer to create detailed cross-sectional images of the shoulder, arm, elbow, forearm, wrist, or hand. The exact area scanned is selected based on your symptoms and the information your clinician provides.

Why might I need this test?

Your clinician may order this scan to evaluate a suspected fracture, joint injury, infection, inflammation, or a mass. It may also be used when the results of standard X-rays are unclear or when detailed assessment of bones and soft tissues is needed.

How is the test performed?

You will lie on a padded table while a CT scanner rotates an X-ray source around the area being examined. The scan is quick and does not hurt, although you may be asked to hold still or briefly hold your breath. No IV contrast dye is used.

How do I prepare for the test?

No fasting is usually required for a scan performed without contrast. Remove jewelry, watches, hairpins, and other metal objects from the area being scanned, and tell the imaging staff if you are pregnant, have an implanted device, or cannot remain still. Follow any specific instructions provided by your healthcare facility.

Frequently asked questions

Is this the same as a regular X-ray?
No. A CT scan uses multiple X-ray measurements and a computer to create cross-sectional images, which can show bones and surrounding soft tissues in more detail.
Will I receive an IV contrast dye?
No. This test is specified as being performed without contrast, so no IV dye is expected. The imaging team will confirm the plan before the scan.
Is the CT scan safe?
CT scans use ionizing radiation, but the scan itself is generally well tolerated. The imaging staff will screen for relevant concerns, including pregnancy, and explain the procedure before it begins.
