Computed Tomography (CT) Pelvis with Reconstruction

What Is a CT Pelvis Scan Used For?

A CT pelvis scan is typically ordered to investigate symptoms such as pain, trauma, or suspected conditions like fractures, tumors, infections, or structural abnormalities in the pelvic region. It may also be used before surgery or to monitor chronic conditions like arthritis or bone diseases. Doctors may also request this scan to evaluate unexplained symptoms like unexplained weight loss, persistent pain, or abnormal lab results related to the pelvic area.

How Is the CT Pelvis Scan Performed?

You’ll lie on a table that slides into a cylindrical machine. A special dye may be injected to highlight blood vessels, and you’ll need to hold still during the scan to avoid motion blur. The scan takes about 15–30 minutes, and you’ll be able to return to normal activities afterward unless instructed otherwise.

What to Expect Before the Scan

No special preparation is usually needed, but you may be asked to remove jewelry, clothing, or metal objects that could interfere with the scan. If you’re pregnant, have a pacemaker, or have allergies to contrast dye, let your doctor know beforehand. Avoid eating or drinking for 4–6 hours if dye is used.

What Are the Possible Risks?

The primary risk is exposure to low-dose radiation, though modern scanners minimize this. Rarely, allergic reactions to contrast dye can occur. If you have kidney issues, your doctor may adjust your preparation to reduce dye load.
