About The Test
What is CT PNS Axial/Coronal Views?
CT PNS stands for Computed Tomography of the Para-Nasal Sinuses. The “Axial” slice shows cross-sections from top to bottom, while the “Coronal” slice displays front-to-back views. Together, they create a high-resolution 3D map of your sinus cavities, septum, and drainage pathways.
When and Who Needs to Take a CT PNS Axial/Coronal Views Scan?
- Persistent nasal congestion or facial pain lasting >12 weeks
- Repeated sinus infections (more than 4 per year)
- Suspected nasal polyps or structural blockage
- Planning for sinus or septal surgery
- Recent facial trauma or suspected sinus fracture
List of Parameters
Axial View
- Taken parallel to the hard palate
- Best for evaluating the sphenoid and posterior ethmoid sinuses
Coronal View
- Taken perpendicular to the nasal floor (like looking at the face straight on)
- Ideal for assessing the osteomeatal complex and frontal sinuses
Combined Axial + Coronal Protocol
- Merges both orientations for a 360° sinus map
- Standard at Cadabams Diagnostics—no extra cost or time
3. List of Parameters Considered During the CT PNS Axial/Coronal Views Scan
| Parameter | What We Look For |
|---|---|
| Sinus cavity opacification | Clouding that suggests infection or polyps |
| Mucosal thickening | Swelling lining the sinus walls |
| Septal deviation | Shift in the nasal septum that blocks airflow |
| Osteomeatal complex patency | Whether key drainage pathways are open or clogged |
Why This Test
- Chronic sinusitis evaluation
- Nasal polyps detection
- Pre-surgical planning for FESS (Functional Endoscopic Sinus Surgery)
- Trauma assessment after sports injuries or accidents

Procedure for Taking a CT PNS Axial/Coronal Views Scan
- Lie on the scanner table; head in a soft holder.
- Stay still for 5–10 seconds while the gantry rotates.
- Breathe normally—the machine does the rest.
Caution Before the Scan
- Pregnancy: Postpone if possible
- Contrast allergy: Rarely used; let us know if you have iodine sensitivity
Test Results
Results and Interpretations
| Finding / Observation | Description | General Interpretation / Significance |
|---|---|---|
| Air-filled sinuses | Normal | No action needed |
| Mucosal thickening | Active sinusitis | ENT consult + medication |
| Complete opacification | Severe infection/polyps | ENT referral, possible surgery |
| Septal spur | Deviated septum | Septoplasty evaluation |
Risks & Limitations
- Radiation dose: Low (≈0.3 mSv), roughly equal to 2 months of natural background exposure.
- Limitations: Soft-tissue swelling can sometimes hide very small polyps; contrast is rarely needed, but discuss allergies if recommended.
- Pregnancy: Inform staff—scans are postponed in the first trimester unless urgent.
