Is an imaging test that uses a small amount of radiation to visualize details of your sinuses. Sinuses are paired (right and left) air-filled pockets that circumscribe the nasal structures. They clean the air breathed through the nose and provide shape to the face.
Tell your doctor if you are or think you are pregnant. You will be asked to remove all jewelry.
You are asked to sit in a chair so that any fluid in the sinuses can be seen in the x-ray images. The technologist may place your head in different positions as the images are taken.
