What is this test?

A hip CT scan uses X-rays and a computer to produce detailed pictures of the hip joint, pelvis, and surrounding tissues. The term “without contrast” means no injected contrast dye is used.

Why might I need this test?

Your clinician may order this scan to evaluate hip pain, a suspected fracture, joint degeneration, inflammation, infection, or an injury involving the surrounding bones and soft tissues. It may also help plan or monitor treatment.

How is the test performed?

You will lie on a padded table while a CT scanner rotates around the affected hip. The scan is generally painless and usually takes only a short time, although you may be asked to remain still.

How do I prepare for the test?

No contrast-related preparation is usually needed. Wear comfortable clothing without metal fasteners and remove jewelry, belt buckles, and other metal objects near the scan area. Tell the imaging team if you are pregnant, may be pregnant, or have had prior reactions to contrast material.

Frequently asked questions

Does this CT scan use contrast dye?
No. “Without contrast” means no injected contrast dye is used for this examination. Tell the imaging team about any prior contrast reactions, although they are especially relevant if another scan with contrast is planned.
Is a hip CT scan painful?
The scan itself is not painful. You may feel brief discomfort from the hard table or when the scanner holds your leg in position, but tell the technologist if anything feels wrong.
Do I need to fast for this test?
Fasting is usually not required for a CT scan without contrast. Follow any specific instructions from your ordering clinician, particularly if you have diabetes, kidney disease, or other medical conditions.
