Doctor examining a patient's nose

Sinus problems can be identified with X-rays or CT scans. A black sinus indicates good health with no mucosal layer, while gray areas can indicate thickening due to chronic sinusitis. Swelling and redness around the eyes can also be signs of severe sinus infections. Examining the sinuses can be challenging. Therefore, CT scans are essential in detecting sinus infections.

What is a Sinus CT Scan?

Using X-ray technology and advanced computer analysis, a computed tomography scan of your sinuses (CT or CAT) is a highly effective way to obtain detailed sinus images. This procedure is crucial in evaluating any damage, infection, or irregularities your doctor may need to address. With CT scans, it is possible to diagnose:

  • Sinus inflammation
  • Headaches caused by sinuses
  • Infections of the sinuses and sinusitis

Additionally, CT scans are helpful for:

  • Examining the nose for polyps, tumors, or cysts
  • Sinus congestion examination
  • Examining the nasal cavity and sinuses before starting any treatment

​​When is a CT Scan Required?

We highly recommend a CT scan in case of a sinus blockage with an unknown cause. This diagnostic approach will allow us to identify any fluid-filled or thick-membraned sinuses, inflammation-causing disorders, and growths in the nasal cavity. With a comprehensive sinus diagram generated from a CT scan, our providers at Texas E.N.T. Specialists can confidently determine the appropriate treatment for you.

How is a CT Scan Performed?

Throughout the procedure, a highly skilled technologist will expertly guide you to the exam table and thoroughly explain the process. If contrast dye is required, it will be administered through your IV without interruptions. A metallic taste and warmth are typical during injections. However, please immediately inform the technologist if you experience any itching, sneezing, nasal congestion, scratchy throat, or facial swelling. The scan involves two parts. Firstly, you will lie on your back with your arms at your sides and head in a holder. It is vital to remain completely still while the table moves into the scanner, which has an open front and back. The technologist will be present throughout the exam, ensuring your safety. During the second set of images, your head will rest on your chin while on your stomach. Typically, it takes around 15 to 30 minutes to complete the procedure.

What Can You Expect?

Although CT scanning of the sinuses may cause some discomfort due to the need to remain still for a few minutes, it is painless. If you experience difficulties staying still or have claustrophobia or chronic pain, rest assured that our team is well-equipped to ensure your comfort, including providing medication. This procedure offers valuable insights into your condition, allowing us to develop a highly effective treatment plan to improve your health.
