A sinus X-ray is an imaging test that uses X-rays to look at your sinuses. The sinuses are air-filled pockets (cavities) near your nasal passage.
X-rays use a small amount of radiation to create images of your bones and internal organs. X-rays are most often used to find bone or joint problems, or to check the heart and lungs. A sinus X-ray is one type of X-ray.
A sinus X-ray is simple and quick, and does not involve any instruments that are put into your body (noninvasive). It can give your healthcare provider useful information. But a sinus X-ray can only tell your provider that a problem exists. It does not show a specific cause of the problem.
