What is this test?
A right shoulder CT scan uses X-rays and computer processing to create detailed cross-sectional images. Contrast material may be given through a vein to improve the visibility of blood vessels and certain tissues.
Why might I need this test?
Your clinician may order this scan to evaluate a suspected fracture, persistent shoulder pain, joint degeneration, infection, a bone lesion, or a problem involving the surrounding muscles and other soft tissues.
How is the test performed?
You will lie on a table while a CT scanner rotates around your shoulder. If intravenous contrast is used, it is usually injected through a small IV line before the images are taken. The scan is generally painless and usually takes less than 30 minutes.
How do I prepare for the test?
Wear comfortable clothing that does not cover the shoulder with metal or thick fabric. Tell the imaging staff if you have previously reacted to contrast, have kidney disease, are pregnant or may be pregnant, or take medicines that may interact with contrast, such as metformin or blood thinners. Follow your clinician's specific instructions.
Reference range
