What Is CT PNS?
A CT PNS scan captures detailed images of your sinuses using advanced X-ray technology. The scan is quick, painless, and highly accurate, allowing doctors to visualize even small changes in sinus tissues, bone, or air spaces. It helps diagnose conditions like sinusitis, polyps, blockages, tumors, or injuries that regular X-rays may miss.
Why Do Doctors Recommend CT PNS?
- Early & Accurate Diagnosis: Detects sinus infections, inflammation, cysts, polyps, and tumors with precision.
- Treatment Planning: Guides ENT specialists in planning surgeries or targeted therapies.
- Chronic Symptoms: Clarifies causes of persistent nasal congestion or facial pain not explained by other tests.
- Injury Assessment: Identifies fractures or trauma after accidents.
What to Expect During the Scan
The procedure is simple:
- You may be asked to remove jewelry or metal objects.
- You will lie on the CT table, usually on your back.
- The scan typically lasts 5–10 minutes.
- No pain; you just need to stay still.
Most patients can resume normal activities immediately after the scan.
