What is this test?

This test is a computed tomography (CT) scan of the mandible, the bone that forms the lower jaw. Intravenous contrast may be given to improve the visibility of blood vessels, inflammation, and certain types of tissue abnormalities.

Why might I need this test?

A mandible CT may be ordered to evaluate jaw pain, swelling, a suspected fracture, an infection, a bone lesion, or changes affecting nearby structures. It can also help guide procedures or treatment planning.

How is the test performed?

You will lie on a CT table while the scanner takes pictures from several angles. If IV contrast is used, it is given through a vein in your arm; the scan itself is painless, and you may be asked to hold still or briefly hold your breath.

How do I prepare for the test?

Follow the instructions provided by the imaging center. Tell the care team if you have previously reacted to iodinated contrast, have kidney disease, are pregnant or may be pregnant, or are taking medicines that could affect kidney function.

Frequently asked questions

Is a CT scan of the mandible the same as a dental X-ray?
No. A dental X-ray focuses on the teeth and nearby jawbone, while a CT scan provides detailed cross-sectional images that can also evaluate deeper bone and surrounding structures.
Is the CT scan painful?
The scan is generally painless. The IV contrast injection may cause a brief warm or flushing sensation, and the technologist will instruct you when to remain still or hold your breath.
Will I need IV contrast?
This test is named as a contrast study, so IV contrast is likely used. The imaging center will confirm the preparation instructions and whether any additional non-contrast images are needed.
