PNS/SKULL X-RAY SCAN

The PNS/Skull X-Ray Scan is a painless imaging test that captures detailed pictures of your paranasal sinuses (PNS) and skull bones. Whether you’re battling recurrent sinusitis or a recent head injury, this scan offers a quick snapshot of possible blockages, infections, or fractures. Cadabams Diagnostics leverages digital radiography to keep radiation exposure minimal while ensuring crystal-clear images.

What is PNS/Skull X-Ray Scan?

Definition & Technology Used

A PNS/Skull X-Ray Scan uses low-dose ionizing radiation to create black-and-white images of your sinuses, nasal cavity, and cranium. Our digital detectors convert X-rays into instant digital images, reducing repeat scans and shortening your visit.

Difference from CT/MRI of Sinuses

• X-ray: 2D, 2–5 mins, lower cost, ideal for screening.
• CT: 3D, higher radiation, best for complex sinus disease.
• MRI: No radiation, superior soft-tissue detail, higher cost.
