What is this test?

A computed tomography (CT) scan creates detailed cross-sectional images of the abdomen. Contrast, usually an iodine-based material given through a vein, may help make blood vessels and certain organs easier to see.

Why might I need this test?

An abdominal CT with contrast may be ordered to evaluate unexplained abdominal pain, injury, infection, inflammation, or an abnormal mass. It can also help assess conditions involving the liver, kidneys, pancreas, bowel, blood vessels, and nearby structures.

How is the test performed?

You lie on a table while a CT scanner rotates around you and takes X-ray images. If contrast is required, it is usually injected into a vein, 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. You may need to avoid eating or drinking for a specified period and may be asked about allergies, kidney disease, pregnancy, medications, and prior contrast reactions.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Abnormal findings may reflect conditions such as infection, inflammation, injury, obstruction, bleeding, or a mass in the abdomen. The radiologist interprets the images in the context of your symptoms and other tests, so an abnormal result does not by itself establish a diagnosis.

Short name

Frequently asked questions

Does “deprecated” mean this CT scan is no longer safe?
No. It usually means the recorded test code or entry is outdated and should not be used for new ordering. Confirm the current procedure and imaging protocol with the ordering clinician or imaging center.
Is iodine contrast the same as the contrast used for some MRI scans?
Usually not. CT contrast is commonly iodine-based, while MRI contrast is commonly gadolinium-based. Tell the imaging center about any prior contrast reaction.
Will the CT scan show everything in the abdomen?
CT provides detailed images of many abdominal organs and structures, but it may not detect every condition. Your clinician may recommend additional or follow-up tests based on the findings.
