Sinus x-ray

• Overview
• Risks

Definition:

A sinus x-ray is a picture of the air-filled cavities in the front of the skull.

Alternative Names:

Paranasal sinus radiography; X-ray - sinuses

How the test is performed:

X-rays are a form of electromagnetic radiation like light, but of higher energy. They can pass through the body to form an image on film. Structures that are dense (such as bone) look white, air looks black, and other structures are shades of gray.

A sinus x-ray is taken in a hospital radiology department or your health care provider's office. You will be asked to sit in a chair so that any fluids in the sinus may be easily seen on the pictures. Your head may be placed in different positions as the pictures are taken.

How to prepare for the test:

Tell your doctor if you are pregnant. Remove all jewelry.

How the test will feel:

Generally, there is little or no discomfort associated with x-rays.

Why the test is performed:

This test is performed when symptoms of sinusitis or other sinus disorders are present.
