What is this test?

A CT scan of the pelvic bones uses X-rays and computer technology to create detailed cross-sectional images of the pelvis. This version is performed without injected contrast dye.

Why might I need this test?

Your clinician may order this scan to evaluate pelvic or hip injuries, locate fractures, assess bone pain, or investigate suspicious bone changes. It may also be used to monitor healing after an injury or orthopedic procedure.

How is the test performed?

You will lie on a table that moves through a CT scanner while X-ray images are taken. The scan is usually painless and generally takes less than 10 to 15 minutes, although the total visit may take longer.

How do I prepare for the test?

No contrast dye or fasting is required for this scan. Wear comfortable clothing without metal fasteners, and tell the imaging staff if you are pregnant, may be pregnant, or have metal implants, a pacemaker, or other implanted medical devices.
