What is this test?

Computed tomography (CT) uses X-rays and a computer to create detailed pictures of the abdomen and pelvis. Intravenous contrast may be injected to improve the appearance of blood vessels and certain organs.

Why might I need this test?

Your clinician may order this scan to evaluate unexplained abdominal or pelvic pain, swelling, fever, injury, or other suspected problems involving the digestive, urinary, reproductive, or vascular systems.

How is the test performed?

You will lie on a moving table while the CT scanner takes X-ray images. If contrast is used, it is usually injected into a vein in your arm, and the scan may include images before and after the injection.

How do I prepare for the test?

Follow the instructions provided by the imaging center, including any fasting or medication guidance. Tell the care team about pregnancy, kidney disease, prior contrast reactions, and allergies to iodine or contrast media before the scan.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Abnormal findings may indicate conditions such as infection, inflammation, bleeding, injury, obstruction, stones, or a mass. The results should be interpreted by a radiologist in the context of your symptoms and other tests.

Frequently asked questions

Does the CT scan use radiation?
Yes. CT imaging uses X-ray radiation, but the scan is generally brief and is performed only when the expected diagnostic benefit outweighs the radiation exposure.
What is intravenous contrast used for?
Intravenous contrast can make blood vessels and certain organs easier to see. It may cause a brief warm sensation, and serious reactions are uncommon.
Will I need someone to drive me home?
Most people can leave normally after the scan. If you received sedating medication, your care team may advise another person to drive you home.
