A PNS axial coronal sagittal CT scan is a computed tomography examination of the paranasal sinuses that acquires images and reconstructs them in axial, coronal and sagittal planes. It provides detailed bone and soft-tissue views to detect sinusitis, mucosal thickening, polyps, fractures, obstructed drainage pathways or tumors, and helps surgical planning and treatment monitoring with high spatial resolution and rapid acquisition.

Axial CT produces horizontal (transverse) cross-sectional images sliced from head to feet, giving stacked "slices" useful for brain, chest and abdominal evaluation. Coronal CT provides vertical, frontal-plane images dividing front and back, useful for sinuses, facial bones, spine alignment and chest/lung assessment. Coronal views are often reformatted from axial data to visualize anatomy in a different orientation.

A PNS CT scan (paranasal sinuses CT) is a noninvasive imaging test using X-rays to produce detailed cross-sectional images of the sinuses, nasal passages and surrounding bones. It helps diagnose sinusitis, polyps, fractures, tumors and complications, and is often used to plan surgery. The exam is quick, typically done without contrast, and shows high-resolution detail of air spaces, mucosa and bone.

A paranasal sinus (PNS) CT scan is generally painless and noninvasive. You lie on a table while the scanner rotates; most people feel no discomfort. If intravenous contrast is used, you may have a brief sting at the injection site or a warm flushing sensation. Rare allergic reactions or claustrophobia-related anxiety can occur—tell staff if you’re worried.

CT PNS (paranasal sinuses) costs vary by country and setting. Typical private ranges: India ₹500–5,000; United States $300–2,000; United Kingdom (private) £150–400; Australia AUD $100–800. Public healthcare or insurance often reduces or covers the fee. Extra charges for contrast, urgent scheduling or radiologist reporting may increase the total. Always check local providers for exact pricing.

Yes — a CT scan of the paranasal sinuses can detect mass lesions, bone destruction, and calcifications that suggest tumors, and it helps define extent and guide biopsy or surgery. However, CT has limited soft‑tissue contrast and may miss intracranial or perineural spread; MRI is better for soft‑tissue assessment. Definitive diagnosis requires tissue biopsy.
