What is this test?

A wrist CT is a computed tomography scan that creates detailed cross-sectional images of the bones and surrounding tissues. “Without contrast” means that no intravenous contrast dye is used.

Why might I need this test?

Your clinician may order this test to evaluate a suspected wrist fracture, complex bone injury, arthritis, bone abnormality, or a persistent wrist problem when standard X-rays are not conclusive.

How is the test performed?

You will lie on a table with your wrist positioned inside the CT scanner. The scanner uses X-rays to take images from different angles, and you will usually be asked to remain still. The procedure is quick and generally does not cause pain.

How do I prepare for the test?

Remove jewelry, watches, and other items near the wrist before the scan. Fasting is usually not required. Tell the imaging team if you are pregnant, may be pregnant, or have had a reaction to contrast dye previously.

Frequently asked questions

Is a wrist CT the same as an X-ray?
No. A standard X-ray creates a two-dimensional image, while CT combines multiple X-ray views to provide more detailed cross-sectional images.
Does a CT scan without contrast use any dye?
No intravenous contrast dye is used for this version of the scan. Some wrist problems may require a different CT protocol with contrast, depending on the reason for the test.
Is a wrist CT painful or unsafe?
The scan is generally painless, but it uses ionizing radiation. The dose is kept as low as reasonably achievable, and the imaging team will screen for relevant risks before the procedure.
