What is this test?

A CT scan of the orbits and face uses X-rays and a computer to produce cross-sectional images of the eye sockets, facial bones, sinuses, and nearby soft tissues. This version is performed without injected contrast dye.

Why might I need this test?

Your clinician may order this scan to evaluate facial or orbital trauma, swelling, persistent sinus symptoms, suspected infection, foreign objects, or abnormal growths. It can also help assess the bony boundaries around the eyes and other facial structures.

How is the test performed?

You will lie on a table while a CT scanner rotates around your head and face. The scan is generally painless and usually takes only a few minutes, although you may be asked to remain very still.

How do I prepare for the test?

No contrast dye is used, so there is usually no need to stop medicines or fast for this scan. Remove glasses, hearing aids, jewelry, hairpins, and other metal items near the scanned area, and tell the technologist if you are pregnant or may be pregnant.

Frequently asked questions

Is contrast dye used in this CT scan?
No. The term “without contrast” means that no intravenous contrast dye is injected for this examination.
Is a CT scan of the face painful?
The scan itself is generally painless. You may feel brief pressure from the body of the scanner, and you must remain still so the images are clear.
Will I be able to drive after the test?
Most people can drive home after a CT scan without contrast. If you received sedation for another reason or your clinician gives specific instructions, follow those instructions.
