What is this test?

A shoulder CT without contrast is an imaging test that creates detailed cross-sectional pictures of the shoulder. It can help evaluate bones, joints, and surrounding soft tissues without injecting iodinated contrast.

Why might I need this test?

Your clinician may order this scan to investigate shoulder pain, an injury, a suspected fracture, joint problems, or abnormalities that are not clearly visible on standard X-rays. It may also be used to plan treatment or surgery.

How is the test performed?

You will lie on a table while an X-ray machine rotates around the affected shoulder. Multiple images are taken and reviewed by a radiologist. Because no contrast is used, there is no need for an injection before the scan.

How do I prepare for the test?

Usually, no special preparation is required. Wear comfortable clothing and remove jewelry, metal objects, and removable items near the shoulder. Tell the imaging staff if you are pregnant, may be pregnant, or cannot remain still during the scan.

Reference range

Adult: 0.4-4.0 mIU/LN/A

Specimen: serum

Take your thyroid medication after the blood draw if applicable. No fasting required.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Abnormal findings may include a fracture, dislocation, joint narrowing, bone changes, or another structural problem. Some findings may help explain pain or guide orthopedic treatment. Your clinician should interpret the results together with your symptoms, examination, and other imaging.

Frequently asked questions

Does this CT scan use contrast?
No. This test is performed without intravenous contrast, so you should not need an injection or a contrast-related preparation.
Is a CT shoulder scan the same as an X-ray?
Both use X-rays, but CT creates many detailed cross-sectional images. CT can show complex bone and joint structures more clearly than a standard X-ray.
Will I need to stay in the hospital?
Most shoulder CT scans are outpatient procedures. You can usually leave after the images are taken, although your clinician may discuss the results at a later visit.
