What is this test?

A computed tomography (CT) scan creates detailed cross-sectional images of the abdomen. Intravenous contrast is a dye injected into a vein to help the spleen, blood vessels, and nearby organs appear more clearly.

Why might I need this test?

Your clinician may order this scan to investigate abdominal pain, spleen injury, unexplained enlargement, fever, or suspected bleeding. It may also be used to evaluate a suspicious area found during another examination or to monitor a known spleen condition.

How is the test performed?

You will lie on a table that moves through the CT scanner while X-ray images are taken. If contrast is used, it is usually injected through 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 facility. Fasting is not always required, but you may be asked not to eat or drink beforehand. Tell the care team about prior contrast reactions, kidney disease, pregnancy, allergies, and any medicines you take; do not stop medication unless instructed.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Abnormal findings may include enlargement, injury, bleeding, infection or inflammation, cysts, fluid collections, or a mass. The results are interpreted together with your symptoms, medical history, physical examination, and other tests, and a radiologist may recommend additional imaging or follow-up.

Frequently asked questions

Is this the same as an ultrasound?
No. A CT scan uses X-rays to create detailed cross-sectional images, while an ultrasound uses sound waves. Your clinician may use one or both depending on the reason for the examination.
Why is intravenous contrast used?
The contrast helps highlight the spleen, blood vessels, and surrounding organs so abnormalities may be seen more clearly. Tell the care team if you have had a previous reaction to contrast.
Does a CT scan use radiation?
Yes. CT imaging uses a small amount of ionizing radiation. The radiation dose is generally low for a routine abdominal CT and is considered when the expected information is useful for your care.
