A CT scan of the wrist is a noninvasive imaging test that uses X-rays and computer processing to produce detailed cross-sectional images of wrist bones and joints. It’s particularly useful for detecting fractures, complex joint injuries, bone fragments, and some bone lesions. The exam is quick, may rarely use intravenous contrast, and involves a small amount of radiation exposure.

A wrist CT scan usually takes about 5–15 minutes for the imaging itself. Including check‑in, positioning and any contrast preparation (rare for wrist), the total appointment typically lasts 15–30 minutes. If extra views or delayed images are needed, it can extend to 30–45 minutes. You’ll be asked to remove jewelry and remain still during the short scan.

Yes — a CT scanner uses a ring-shaped gantry with an opening; the patient lies on a table that slides through, so both ends of the scan tunnel are open. It’s generally less enclosed than a closed-bore MRI. Modern wide-bore and open CT designs further increase comfort and make patient access easier during scanning.

Initial evaluation of wrist pain usually starts with plain X-rays to detect fractures or arthritis. If X-rays are normal but symptoms persist or ligament/soft-tissue injury is suspected, MRI is the best next scan for visualizing ligaments, TFCC, cartilage, bone bruises, and occult fractures. CT is preferred for detailed bone anatomy or complex fracture planning; ultrasound can assess tendons dynamically.

MRI is generally better for wrist soft-tissue evaluation—ligaments, tendons, cartilage, and bone‑marrow changes—and avoids ionizing radiation. CT provides superior detail of bone architecture and is preferred for small or complex fractures and surgical planning. Choice depends on the suspected problem, presence of metal or MRI contraindications, urgency, and local availability; clinicians select the modality that answers the diagnostic question.

A CT scan itself is generally painless. You lie on a table that moves through the scanner; remaining still may cause discomfort or anxiety. If contrast dye is injected you may feel brief stinging, a warm flushing sensation, or mild pressure at the IV site. Serious pain or allergic reactions are rare—inform staff about allergies, kidney issues, or pregnancy before the scan.
