CT Upper Extremity, Limited, With Intravenous Contrast

What is this test?

This is a limited computed tomography (CT) examination of part of an upper extremity, such as the shoulder, arm, elbow, forearm, wrist, or hand. Intravenous contrast may be used to improve the visibility of blood vessels and certain soft tissues.

Why might I need this test?

A limited CT scan may be ordered to evaluate a suspected fracture, complex joint or bone injury, infection, inflammation, tendon or ligament problem, tumor, or another structural abnormality. It can also provide additional detail when standard X-ray findings are inconclusive.

How is the test performed?

You lie on a CT table while the scanner takes X-ray images from multiple angles. If contrast is used, it is usually injected into a vein in your arm before the scan. The examination is generally painless, although staying very still is important.

How do I prepare for the test?

Follow the imaging center's instructions about eating, drinking, medications, and the timing of the scan. Tell the care team if you have previously reacted to contrast, have kidney disease, are pregnant or may be pregnant, or have other relevant medical conditions.
