What is this test?

A salivary gland CT scan creates detailed X-ray images of the major salivary glands in the neck and the tissues around them. This version is performed without intravenous contrast dye.

Why might I need this test?

The scan may be recommended to evaluate a swollen or painful gland, a suspected salivary stone, or a lump in the neck or jaw area. It can also help assess inflammation, cysts, infection, or other structural abnormalities.

How is the test performed?

You will lie on a CT table while a scanner rotates around your head and neck to take X-ray images. The procedure is painless and usually takes only a few minutes, although the total visit may take longer.

How do I prepare for the test?

Because no intravenous contrast is used, fasting is usually not necessary, but the imaging center may have specific instructions. Remove jewelry, glasses, hearing aids, and other metal items from the head and neck area before the scan, and tell the technologist if you are pregnant or may be pregnant.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Abnormal findings may indicate a salivary stone, gland enlargement, inflammation, infection, a cyst, or a mass. A CT scan can also show whether a nearby structure is affecting a gland or salivary duct. The radiologist's interpretation should be reviewed with your healthcare professional and considered alongside your symptoms and examination.

Frequently asked questions

Does this CT scan use contrast dye?
No. This test is performed without intravenous contrast, so you generally will not need an injection or a contrast-related wait before the scan.
Is a salivary gland CT scan painful?
The scan itself is painless, but you may feel brief pressure or tightness from the table and scanner. The technologist can explain what to expect and help you remain comfortable.
Can this test detect salivary stones?
Yes. CT imaging is useful for locating salivary stones and assessing related blockage or inflammation, particularly when the stone's location or cause of symptoms is unclear.
