What is a CT PNS Scan?
Specifically, a CT PNS (Paranasal Sinuses) scan evaluates your nasal cavity and surrounding air sinuses in high detail. Furthermore, our advanced scanners capture rapid coronal and axial pictures to detect chronic sinusitis, nasal polyps, mucosal thickening, or bone deviations.
Therefore, doctors consider it an essential diagnostic tool for chronic sinus issues and surgical planning. For more detailed clinical information, you can read the RadiologyInfo guide on sinus CT imaging. Similarly, if you need intracranial soft tissue evaluation instead, you might prefer a brain MRI scan.
Before Your CT PNS Scan, Please Bring:
In order to ensure a smooth appointment, please review the required documents and preparation steps listed below.
- Doctor’s prescription: Valid referral from a registered medical practitioner.
- Previous reports: Past sinus X-ray, CT, or nasal endoscopy reports for clinical comparison.
- Blood test reports: Recent Serum Creatinine/eGFR report (done within 30 days) if contrast is planned. You can book this routine blood test with us or learn more from the Mayo Clinic guidelines.
- Medications & History: List of current medications and relevant medical history (allergies, prior nasal surgeries).
- Insurance documents: If applicable, bring your insurance ID card and photo ID for cashless processing.
Is Contrast CT PNS Scan Safe?
Meanwhile, most routine sinus scans are performed plain without contrast, though specialized evaluations may require an intravenous contrast agent. Before contrast administration, our team reviews relevant medical history and kidney function information when clinically appropriate. Patients should inform the imaging team about previous contrast reactions, kidney disease, pregnancy, or other relevant medical conditions.
CT PNS Scan Radiation Safety & Quality Standards
Furthermore, CT imaging involves ionizing radiation. Our facility follows applicable radiation safety requirements and established protocols designed to minimize unnecessary radiation exposure while maintaining diagnostic image quality.
Consequently, we maintain rigorous NABH, NABL, and AERB compliance standards to guarantee maximum safety for every patient visiting our center.
