What is this test?

This is a computed tomography (CT) examination that creates detailed X-ray images of the abdomen and chest. Intravenous contrast dye may be used to improve the visibility of blood vessels, organs, and other tissues.

Why might I need this test?

A clinician may order this scan to evaluate unexplained symptoms, investigate an abnormal finding, or monitor a known condition. It may be used to assess organs, blood vessels, lymph nodes, infection, bleeding, injury, stones, or masses.

How is the test performed?

You will lie on a table while a CT scanner rotates around you and takes X-ray images. If contrast is required, it is usually injected through a vein in your arm; the scan is generally painless and usually takes less than an hour.

How do I prepare for the test?

Follow the instructions provided by the imaging center, which may include fasting for part of the examination. Tell the care team about contrast allergies, kidney disease, pregnancy, and any medicines you take, because these factors may affect the scan or its safety.

Frequently asked questions

Does this test use radiation?
Yes. CT scans use a small amount of ionizing radiation to create detailed images. The radiologist and your care team will consider the clinical need for the examination.
Is the CT scan painful?
The scan itself is generally painless. An IV needle may be used for contrast, and you may be asked to briefly hold your breath while images are taken.
When will I receive the results?
A radiologist will interpret the images and send a report to your ordering clinician. Your healthcare professional may contact you to discuss the findings, so ask when and how results will be communicated.
