What is this test?

A limited CT scan uses X-rays and a computer to create detailed pictures of part of the abdomen. This version is performed without iodinated contrast injected into a vein.

Why might I need this test?

It may be ordered to investigate unexplained abdominal pain, swelling, nausea, vomiting, fever, or other acute symptoms. It can help identify conditions affecting the bowel, appendix, kidneys, bladder, and nearby structures.

How is the test performed?

You will lie on a table that moves through a CT scanner. The scanner takes several X-ray images from different angles, which are combined to show structures inside the abdomen. The scan is generally painless and usually takes a short time.

How do I prepare for the test?

Follow the imaging center's instructions because preparation may vary. You may be asked not to eat or drink for a short period. Tell the staff if you are pregnant, have kidney problems, or have had a reaction to contrast, even though contrast is not used in this version of the scan.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

The scan may reveal inflammation, obstruction, perforation, fluid collections, stones, masses, or other abnormalities in the abdomen. Findings are interpreted together with your symptoms, physical examination, and other tests. A radiologist will provide the results to your ordering clinician, who will explain what they mean for your care.

Frequently asked questions

Does this CT scan use contrast?
No iodinated contrast is injected into a vein for this scan. Some facilities may still use an oral contrast product, so confirm the instructions with the imaging center.
Is a limited abdominal CT the same as a full-body CT?
No. A limited CT focuses on the abdomen and uses fewer images than a scan covering a larger area of the body.
Will I feel anything during the scan?
The scan itself is usually painless. You may be asked to hold your breath briefly while the images are taken, and the scanner can feel tight in narrow spaces.
