Please continue reading to learn more about sinus CT scans, including the time it takes for the procedure and the distinctions between normal and abnormal sinus CT scans. 


What Does a Sinus CT Scan Show?

A sinus computed tomography scan, or CT scan for short, is a medical imaging procedure that uses X-rays to create detailed cross-sectional images.

This type of imaging is primarily used to visualize the anatomy of the sinuses, which are air-filled spaces in the facial bones that connect to the nasal cavity. 

A sinusitis CT scan provides valuable information about the sinuses' structure and helps identify abnormalities or issues affecting the nasal passages.

This is a valuable tool in diagnosing and understanding various sinus-related conditions, guiding treatment plans, and helping healthcare providers make informed decisions to alleviate symptoms and improve a patient's quality of life.

Can A Sinus CT Scan Show Polyps?

Yes, a sinus CT scan can show polyps.

In fact, they work to effectively visualize and identify nasal polyps, non-cancerous growths that can develop in the nasal and sinus cavities. 

These polyps are often associated with chronic sinusitis and nasal inflammation.

By detecting nasal polyps through a sinus CT scan, your healthcare provider can differentiate them from other conditions with similar symptoms, such as nasal congestion, difficulty breathing, or chronic infections.

Can A Sinus CT Scan Detect a Brain Tumor?

No, a CT scan of the sinuses cannot typically detect or confirm the presence of a brain tumor.

A sinus CT scan primarily focuses on imaging the sinuses and nearby structures, and it is not the most appropriate imaging option for directly detecting brain tumors. The good news is that other types of CT scans can be used to take images of your brain.


How Do I Prepare for a Sinus CT Scan?

There are various steps to take in preparation for a CT scan of the sinuses. It is essential to follow the specific instructions provided to you by your doctor or interventional radiologist before your scan.

In general, it is best to:

  • Inform your healthcare team about allergies or past reactions to contrast dye.
  • Wear comfortable clothing without metal objects.
  • Tell the technologist about any metal implants or devices.
  • Notify them if pregnant or breastfeeding.
  • Ask for support if you have anxiety or claustrophobia.

A Normal Sinus CT Scan vs. Abnormal CT Scan of the Face

In a normal sinus CT scan, the images will show clear and unobstructed sinus cavities. The main characteristics include:

  • Well-aerated sinuses with no signs of inflammation or infection.
  • A thin mucosal lining 
  • No evidence of nasal polyps, masses, or abnormal growths in the sinus or nasal areas 

In a CT scan of the face, the bony structures, including the nasal septum, turbinates, and orbital bones, will be intact and in their correct positions. 

A normal sinus CT scan results typically indicate healthy nasal anatomy.

On the other hand, an abnormal CT scan of the face may reveal various issues related to the sinuses and surrounding facial structures. These abnormalities can include:

  • Infections
  • Blockages and obstructions in the nasal passages
  • A deviated septum
  • Tumors
  • Trauma in facial bones and sinuses resulting from accidents or injury

Abnormal findings on a CT scan of the face warrant further evaluation and may require additional tests or consultations with an Ear, Nose, and Throat Specialist or other specialist to determine the underlying cause.


Does a Sinus CT Scan Emit Radiation?

Yes, a sinus CT scan emits radiation.

The radiation dose produced during your scan is considered safe, and all efforts are made to keep levels as low as reasonably achievable. 

It is important to inform your healthcare provider if you are pregnant or breastfeeding and require a CT scan, as extra precautions may be needed.
