About The Test
MRI PNS uses magnets and radio waves to create detailed pictures of your sinuses and nasal cavity.
No radiation, no pain—just 20–30 minutes on our comfortable, wide-bore scanner.
Ideal for chronic sinusitis, nasal polyps, and post-surgical checks.
List of Parameters
Maxillary, frontal, ethmoid, sphenoid sinuses for fluid, polyps, or masses
Ostiomeatal complex—the main drainage pathway
Nasal septum & turbinates for deviation or enlargement
Why This Test
Recurrent headaches or facial pain unrelieved by medication
Chronic nasal obstruction affecting sleep or breathing
Unexplained loss of smell or persistent post-nasal drip
When to Take Test
Benefits
Benefits of PNS MRI Scan
No radiation exposure—safe for children and pregnant patients (after first trimester)
High soft-tissue contrast detects even small polyps and early tumours
Same-day reports at Cadabams Diagnostics for faster treatment planning
Conditions Diagnosed by MRI PNS
Acute & chronic sinusitis—fluid levels, thickened lining
Nasal polyps—soft, grape-like growths
Fungal sinus infections—distinctive signal patterns
Sinus tumors—benign and malignant masses clearly outlined
Preparing for test
Pre-requisites
- Remove all metal—jewellery, hairpins, hearing aids
- Fasting for 4 hours only if contrast is planned
Best Time to Take the Test
- Any weekday morning or afternoon slot
- Early booking advised if you need sedation
Eligibility
- Generally safe; pregnant patients beyond the first trimester must bring a doctor’s note
Procedure Step-by-Step
- Check-in at reception (carry doctor’s prescription)
- Change into metal-free gown
- Lie on the scanner table; cushions for comfort
- Scan lasts 20–30 minutes with brief pauses
- Contrast patients rest 10 minutes post-injection for observation
Caution Before the Test
- Report contrast allergies or kidney issues—we check creatinine levels if needed
Test Results
Results and Interpretations of PNS MRI Scan
| Finding / Observation | Description | General Interpretation / Significance |
|---|---|---|
| Normal | Clear sinuses, thin mucosal lining | No active disease |
| Mucosal thickening | Swelling >4 mm | Suggests sinusitis |
| Polyp | Round soft-tissue mass | May need surgery if symptomatic |
| Fungal ball | Hypointense round mass | Usually non-invasive, can be removed |
| Tumour | Irregular enhancing mass | Further ENT evaluation required |
| Bone Erosion / Remodeling | MRI shows loss or thinning of sinus bony walls; best confirmed on CT. | Seen in aggressive infections (e.g., fungal), chronic inflammation, or tumors. Requires urgent ENT or surgical evaluation. |
| Contrast Enhancement | Tissues show increased signal intensity after contrast, indicating vascularity. | Helps identify abscesses, enhancing tumors, or active inflammation. Non-enhancing areas suggest fluid or necrosis. |
| Involvement of Adjacent Structures (Orbit, Brain) | Extension of disease beyond the sinuses into nearby structures like orbits or intracranial space. | Suggests complicated sinusitis (e.g., orbital cellulitis, abscess), fungal invasion, or malignancy. Urgent intervention often needed. |
Risks & Limitations
- Metal implants or pacemakers may be unsafe; our technologists screen every patient beforehand.
- Claustrophobia? Ask for the open-bore option or mild sedation (requires fasting).
- Cost vs CT: MRI PNS is slightly higher priced but avoids radiation—valuable for children and repeated studies.
FAQs
How long does an MRI PNS take?
About 20–30 minutes; add 15 minutes if contrast is used.
Is MRI PNS painful?
No. You only need to lie still. Earplugs reduce machine noise.
Can I eat before an MRI PNS?
Yes, unless contrast is scheduled—then fast for 4 hours.
When will I get my report?
Same day by 7 p.m. for scans before 2 p.m.; next morning for later slots.
What are the next steps after an MRI PNS?
Your referring doctor will review the MRI PNS report and images in conjunction with your symptoms and other medical information. They will then discuss the findings with you, explain what they mean for your specific condition, and recommend appropriate treatment options or any further tests if necessary.
How much does an MRI PNS scan cost?
The PNS MRI scan cost can vary depending on several factors, including the specific type of MRI PNS performed (with or without contrast), geographic location, and your insurance coverage. For precise pricing information for an MRI PNS at Cadabams Diagnostics, it's best to contact our billing department directly or check with your insurance provider regarding coverage and any out-of-pocket expenses.
