What is a CT PNS Scan?
A fast, non-invasive imaging test that creates detailed cross-sectional pictures of all four pairs of paranasal sinuses, the nasal cavity, and surrounding facial structures.
What PNS Stands For
PNS stands for Paranasal Sinuses — the four pairs of air-filled cavities surrounding the nasal passages: maxillary, ethmoid, frontal, and sphenoid sinuses. A CT PNS scan produces highly detailed cross-sectional images of all these sinuses, the nasal cavity, ostiomeatal complex, and surrounding bony structures — far superior to X-ray or MRI for bony detail and surgical planning.
How CT PNS Works
The 160-Slice CT scanner rotates 360° around your head, capturing hundreds of images at different angles. Each sinus — its walls, mucosa, fluid, polyps, and drainage channels — has a different density signature. The computer reconstructs these into razor-sharp axial, coronal, and sagittal cross-sections. Coronal cuts are especially vital as they mirror the surgical approach during FESS.
CT PNS vs X-Ray vs MRI
X-ray (Waters view) only shows the maxillary sinuses and misses ethmoid and sphenoid sinuses entirely. MRI is excellent for soft tissue but poorly defines bony sinus walls and drainage pathways. CT PNS is the only investigation that shows bony anatomy, ostiomeatal complex, mucosal thickening, polyps, drainage blockages, and orbital/intracranial extensions — all in one study.
Is Contrast Needed?
In the vast majority of cases, a plain CT PNS (NCCT) is all that is required. It perfectly evaluates sinusitis, polyps, bony anatomy, and FESS planning without any injection. Contrast CT (CECT PNS) is reserved for suspected sinus tumours, fungal sinusitis with intracranial extension, vascular lesions, or when soft-tissue characterisation is needed beyond bony anatomy.
The Paranasal Sinuses CT Evaluates
Detailed imaging of all four pairs of sinuses — plus the ostiomeatal complex critical for drainage and FESS planning.
Maxillary Sinuses
The largest sinuses, located in the cheekbones on either side of the nose. Most commonly affected in sinusitis.
- Mucosal thickening & fluid levels
- Maxillary sinusitis (acute / chronic)
- Dental-origin sinusitis
- Maxillary sinus cysts & polyps
- Ostium blockage patterns
- Antral washout evaluation
Ethmoid Sinuses
A honeycomb of small air cells between the eyes. Critical for FESS — forms the key surgical landmark.
- Anterior & posterior ethmoid cell opacification
- Ethmoid polyposis
- Ostiomeatal complex (OMC) blockage
- Bulla ethmoidalis anatomy
- Lamina papyracea integrity
- Skull base proximity (Keros classification)
Frontal Sinuses
Located in the forehead above the eyes. Variable in size — sometimes absent. Frontal headache source.
- Frontal sinusitis & mucocele
- Frontal recess anatomy for FESS
- Frontal sinus aplasia / hypoplasia
- Frontal sinus osteoma
- Posterior table integrity
- Intracranial extension assessment
Sphenoid Sinuses
Deep posterior sinuses adjacent to the skull base, pituitary gland, and optic nerves. Rarely but seriously affected.
- Sphenoid sinusitis (rare, serious)
- Sphenoidal mucocele
- Relationship to optic canal & ICA
- Skull base involvement
- Pituitary fossa adjacency
- Invasive fungal sinusitis spread
Ostiomeatal Complex (OMC)
The critical drainage pathway — blockage here causes most cases of chronic sinusitis. The surgical target of FESS.
- Uncinate process morphology
- Middle meatal anatomy
- Maxillary ostium patency
- Infundibular blockage patterns
- Concha bullosa
- Haller cells & agger nasi cells
Nasal Cavity & Septum
The nasal passages and central dividing wall — commonly deviated and affecting sinus drainage.
- Deviated nasal septum (DNS) grading
- Nasal polyps — extent & origin
- Turbinate hypertrophy
- Nasal mass characterisation
- Choanal atresia / stenosis
- Septal spur & perforation
Types of CT PNS Scans Available
We offer the complete range of paranasal sinus CT protocols for every clinical and surgical requirement.
NCCT PNS (Plain)
The gold standard for sinusitis evaluation and pre-FESS surgical planning. No dye injection, no fasting, no preparation needed. Clearly shows mucosal thickening, fluid levels, polyps, bony anatomy, and ostiomeatal complex in all four sinus groups.
CECT PNS (With Contrast)
Contrast-enhanced CT for characterising sinus tumours, angiofibroma, inverted papilloma, fungal sinusitis with orbital/intracranial spread, and vascular lesions. Also used when plain CT findings are equivocal.
CT PNS Pre-FESS Protocol
High-resolution coronal and axial thin-slice CT specifically formatted for ENT surgical navigation. Identifies critical anatomical variants — skull base height, lamina papyracea dehiscence, Keros classification — essential for safe sinus surgery.
CT PNS with Orbits
Combined paranasal sinus and orbital CT for cases with periorbital swelling, proptosis, orbital cellulitis secondary to sinusitis, or ethmoid sinusitis with orbital wall involvement — evaluated in a single scan.
CT PNS + Brain
Combined sinus and brain CT for evaluating intracranial complications of sinusitis — meningitis, brain abscess, cavernous sinus thrombosis — or when neurological symptoms accompany sinus disease.
Post-FESS Follow-Up CT
Post-operative CT evaluation to assess surgical cavity healing, residual mucosal disease, synechiae (adhesions), and recurrent polyps following functional endoscopic sinus surgery — typically at 3–6 months post-op.

Detects Fungal Sinusitis
CT PNS with its bony window settings can identify high-density fungal debris, calcification patterns, and bony erosion — vital in diabetic and immunocompromised patients.
Anatomical Variant Mapping
Identifies concha bullosa, Haller cells, agger nasi cells, Onodi cells, and Keros classification — variants that significantly affect surgical approach and complication risk.
How to Prepare for CT PNS Scan
Great news — plain CT PNS requires virtually no preparation. The easiest imaging test to walk into. Follow these simple guidelines.
Do's – Before Your Scan
- ✓Arrive 15 minutes early for registration — very little else is needed
- ✓Bring your ENT doctor's prescription and any previous X-rays or CT reports
- ✓Inform staff about all medications — especially nasal steroids, anticoagulants
- ✓Tell us if you are pregnant, breastfeeding, or have a known contrast allergy
- ✓Continue your nasal sprays and antihistamines as usual before the scan
- ✓Fast 4–6 hours only if CECT PNS (contrast) has been prescribed
- ✓Mention any history of diabetes — relevant for fungal sinusitis risk assessment
- ✓Stay as still as possible during the scan — very important for sharp images
Don'ts – What to Avoid
- ✗Do NOT eat or drink 4–6 hours before contrast CT PNS (if prescribed)
- ✗Avoid wearing earrings, nose pins, spectacles, or hair accessories
- ✗Do not carry keys, coins, or metal objects into the scan room
- ✗Avoid nose blowing forcefully just before the scan
- ✗Do NOT use nasal decongestant sprays immediately before scan (may mask findings)
- ✗Avoid swallowing or talking during the brief scan period — stay very still
- ✗Do NOT take Metformin 48 hours before and after contrast CT (consult doctor)
- ✗Avoid delaying — chronic sinusitis complications can progress to orbital or brain involvement
What Happens During
Your CT PNS Scan?
One of the quickest and easiest CT scans available — most patients are done in under 15 minutes total.
Check-In & Registration
Present your ENT prescription at reception. Staff verifies your details, prepares your file, and records any allergies, medications, and relevant history — takes just 3–5 minutes.
Remove Metal & Prepare
Remove spectacles, earrings, nose pins, and any metal accessories. For plain CT PNS, no gown change is needed. You simply lie down comfortably on the CT table.
Positioning
You lie on your back on the padded CT table, head in a padded headrest. Your head is positioned in the gantry for both axial and coronal sinus images. The table slides smoothly and quietly.
The Scan (5–10 min)
The gantry rotates silently. Each CT pass takes just a few seconds. You will be asked to keep very still — no breath-holding is usually required for CT PNS, unlike chest scans. The whole scan is complete in minutes.
ENT-Format Report Same Day
Our MD Radiologist prepares a structured, ENT-focused report with Lund-Mackay scoring, anatomical variants, and findings across all sinus groups. Delivered same day via WhatsApp and email for your surgeon.
What the Lund-Mackay Score Means
Our radiologists provide the standardised Lund-Mackay CT Score — the internationally accepted system for grading sinus disease severity. Each sinus group is scored 0 (clear) to 2 (completely opacified), and the ostiomeatal complex 0 or 2. Total score out of 24 guides your ENT surgeon's decision between medical management and surgery. Most ENT surgeons in Ahmedabad require this score before approving FESS.
Sinus Complications Need Urgent CT
Complications of acute sinusitis — orbital cellulitis, subperiosteal abscess, meningitis, or cavernous sinus thrombosis — are medical emergencies. If you have eye swelling, vision changes, severe headache with fever, or neck stiffness alongside sinus symptoms, please walk in immediately. Our CT scanners are available 24 hours for emergency imaging.

What Our Patients Say
Trusted by ENT specialists and patients across Ahmedabad for accurate, detailed sinus imaging.
I had chronic sinusitis for 3 years. My ENT referred me for a CT PNS and the Satellite branch did it the same day. The report included full Lund-Mackay scoring which my surgeon needed for FESS planning. Affordable, fast, and the report quality was excellent!
My child had nasal polyps and the CT PNS clearly showed the extent of involvement. Very affordable — other places were quoting ₹4,000 but Usmanpura did it for much less. The staff was very gentle with my son. Report was ready within hours. Highly recommend!
Needed urgent CT PNS at 10pm for suspected fungal sinusitis — my ENT was worried. The Naroda branch was fully operational and the scan was done immediately. The CT showed the characteristic findings and my surgeon could operate the next morning. Life-saving service!
