CT Scan of the Sinuses

A CT or CAT scan is a shortened name for computerized tomography. A CT scan takes pictures of the inside of the body. The pictures are more detailed than a typical x-ray. During a CT scan of the sinuses, pictures are taken of cross sections or slices of the sinuses. The sinuses are air-filled cavities in your head. CT scans can identify problems with your sinuses. Your doctor will use this information to determine the best treatment for you.

 

Preparing for the Test

  • Avoid doing a nasal wash at least 24 hours before a sinus CT scan.
  • Remove glasses, earrings, hearing aids and dental appliances before the sinus CT scan.

 

During the Test

The CT scan does not hurt. The radiology technologist will explain the CT scan to you before you start. Ask questions if you don't understand. Before the study you/your child will need to remove glasses, earrings, hearing aids and dental appliances.

The CT scanner includes a table you will lie on and a doughnut-shaped ring. You will lie still on the table while it advances through the ring. The technologist will give you instructions during the test. While you hold still the table will move through the ring while pictures are taken. It is important to lie still while the images are taken.

Young children may have trouble lying still during the CT scan. If this is the case, the child may be given medicine to make him or her sleepy first. This is done is the Pediatric Care Unit. If this is done first, a nurse will also be at the CT scan. If you are concerned your young child may not be able to hold still, talk with your doctor before the CT scan.

 

Length of the Test

A CT scan of the sinuses takes about 15 minutes. The actual test will take about 5 minutes.

 

Day of the Test

Your appointment is in radiology. Radiology is on the third floor of the Smith Building. On the day of your test, first report to the Admissions Desk just inside the Main Entrance. Admissions will direct you to the appropriate location for your test.
