A CT PNS Scan (Computed Tomography of Paranasal Sinuses) is an advanced imaging test used to examine the sinus cavities in detail. The paranasal sinuses are air-filled spaces located around the nose, eyes, and forehead. When sinus problems become chronic or severe, doctors recommend a CT PNS scan to find the exact cause and plan proper treatment.
What Is a CT PNS Scan?
A CT PNS scan uses X-ray technology combined with computer imaging to create detailed cross-sectional images of the sinus cavities. Unlike a regular X-ray, this scan provides clear views of bones, soft tissues, and air spaces. It helps detect sinus infections, blockages, inflammation, and structural abnormalities with high accuracy.
Why Is a CT PNS Scan Done?
Doctors may recommend a CT PNS scan for several reasons, including:
Chronic or recurrent sinusitis
Persistent nasal congestion or headache
Facial pain or pressure
Suspected nasal polyps
Blocked sinus drainage
Planning or monitoring sinus surgery
This scan helps identify the exact problem when symptoms do not improve with medication.
CT PNS Scan Procedure
The CT PNS scan procedure is quick and painless:
The patient lies on the CT scan table
The head is positioned correctly for imaging
The scanner rotates around the head to capture images
The entire scan usually takes 5 to 10 minutes
The patient must remain still during the scan for clear images.
Preparation for CT PNS Scan
In most cases, no special preparation is required. However:
Remove metal objects like earrings or hair clips
Inform the technician if you are pregnant
Follow any instructions given by the diagnostic center
If contrast dye is required, additional preparation may be advised, but most CT PNS scans are done without contrast.
Is CT PNS Scan Safe?
A CT PNS scan is generally safe when performed under medical supervision. It uses a low dose of radiation, and modern CT machines minimize exposure. Pregnant women should inform their doctor before undergoing the scan.
Benefits of CT PNS Scan
Provides clear and detailed images
Helps in accurate diagnosis
Useful for treatment and surgery planning
Quick and non-invasive procedure
Helps detect problems missed by X-rays
When Should You Consider a CT PNS Scan?
You should consider a CT PNS scan if you experience:
Long-term sinus symptoms
Repeated sinus infections
Poor response to medications
Severe facial pain or nasal blockage
Early diagnosis can prevent complications and improve quality of life.
Conclusion
A CT PNS Scan is a reliable and effective diagnostic test for identifying sinus-related problems. It helps doctors understand the exact condition of the sinuses and plan the right treatment. With advanced imaging technology and quick results, a CT PNS scan plays an important role in managing chronic sinus issues and improving patient outcomes.
