What is this test?
A CT pelvis is a computed tomography scan that uses X-rays and a computer to create detailed pictures of the pelvic bones, lower spine, hips, and nearby organs and tissues. Contrast material may be used to improve the visibility of blood vessels and certain tissues.
Why might I need this test?
Your clinician may order this scan to evaluate pelvic or hip pain, trauma, suspected fractures, infection, inflammation, stones, or an abnormal growth. It may also be used to plan surgery or treatment and to assess the extent of a known condition.
How is the test performed?
You will lie on a padded table while a scanner takes X-ray images from different angles. Images may be obtained before and after contrast is given through a vein; the exact protocol, including whether oral contrast is needed, depends on the reason for the scan and the imaging center's instructions.
How do I prepare for the test?
Follow your clinician's or imaging center's preparation instructions, which may include fasting or discontinuing certain medicines for a limited time. Tell the care team about any contrast allergy, kidney disease, pregnancy possibility, or recent surgery before receiving contrast.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Abnormal findings may include fractures, joint problems, infection, fluid collections, stones, bowel or urinary abnormalities, or a mass. The meaning of each finding depends on your symptoms, medical history, and the full CT report, so your clinician should interpret the results with you.
