What is this test?

A CT scan creates detailed cross-sectional images of the abdomen and pelvis using X-rays. Contrast may be given by mouth, through a vein, or both, depending on the specific imaging protocol.

Why might I need this test?

This test may be used to investigate abdominal pain, swelling, fever, injury, kidney stones, bowel problems, or unexplained symptoms. It can also help evaluate the condition and extent of a disease or abnormality.

How is the test performed?

You will lie on a moving table while the CT scanner takes X-ray images from different angles. If needed, contrast will be provided, and the scan usually takes only a few minutes, although the overall visit may take longer.

How do I prepare for the test?

Follow the instructions provided for your specific scan, including any fasting or medication guidance. Tell the care team about contrast allergies, kidney disease, pregnancy or possible pregnancy, and medicines such as metformin before the test.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

The scan may reveal conditions such as infection, inflammation, kidney stones, bowel obstruction, injury, cysts, or masses. It can also show narrowing or blockage of blood vessels and changes in the size or appearance of organs. A radiologist will interpret the images and provide the results to your ordering clinician.

Will I receive the results immediately?
The images are usually reviewed by a radiologist after the scan. Your ordering clinician will explain the results and discuss any recommended follow-up.
