When is a CT scan of the sinuses necessary?

A CT scan of the sinuses can help your doctor:

  • Identify the cause of your sinus and nasal symptoms
  • Look for problems and diseases affecting the sinuses
  • Plan for endoscopic sinus surgery

What to expect

During your CT Scan

Before your CT scan, inform your doctor if you are or might be pregnant, are allergic to any medications, or have certain medical conditions, such as heart failure, diabetes and asthma. To prepare for your test, you should wear comfortable, loose-fitting clothing and remove all jewelry, glasses and hearing aids.

Your CT scan will be performed by a radiology technologist and the pictures will be evaluated by a radiologist. In most cases, your ENT will also review the results of your CT scan. During the test, you will lie on a table that is attached to a large machine with a rounded opening. This machine is the CT scanner. Your head will be positioned inside the scanner, which will take photos as it moves. You will hear clicking and buzzing sounds while the machine works and it’s very important to remain still during this process.

You can expect the entire experience to take about 30 to 60 minutes. Most of that time is spent preparing, as the actual scan only takes a few seconds. It is completely pain-free but may be uncomfortable for patients who are claustrophobic. If you get nervous in small spaces, your doctor may administer a sedative before the scan to ensure your comfort.

What are the risks?

When you have a CT scan, you are exposed to ionizing radiation. There is the potential that this exposure could increase your risk of cancer. However, for many patients, the diagnostic benefits of the test far outweigh the potential risks. In addition, SFENTA physicians use the most advanced CT scanners on the market, which use the lowest amount of radiation possible. If you are pregnant, there is a chance that the radiation could harm your unborn baby. As such, your doctor will likely recommend an alternative test, such as an ultrasound or MRI.
