CT PNS coronal is a computed tomography scan of the paranasal sinuses reformatted in the coronal plane. It gives detailed cross-sectional images of sinus anatomy, the ostiomeatal complex, and bony structures, helping diagnose sinusitis, polyps, fungal disease, fractures, or anatomical variants. Coronal views are especially useful for surgical planning and assessing mucosal thickening, obstruction, or complications.

In a CT scan, the coronal view is an imaging plane that slices the body vertically from side to side, producing front-to-back (anterior–posterior) images. It displays structures as if viewing the patient face-on, useful for assessing sinuses, facial bones, spine alignment, and chest or abdominal anatomy. Coronal reconstructions complement axial images to clarify anatomical relationships and pathology.

A CT PNS (computed tomography of the paranasal sinuses) uses X‑rays and computer processing to produce detailed cross‑sectional images of the sinus cavities and surrounding bones. It helps diagnose sinusitis, polyps, fractures, tumors, and aids surgical planning. The scan is quick, noninvasive, and often outpatient. Preparation is minimal (remove metal, lie still); risks include radiation and rare contrast reactions.

A PNS CT scan evaluates the paranasal sinuses and surrounding bones, detecting sinusitis (mucosal thickening, fluid levels), nasal polyps, mucoceles, cysts and masses, bony erosion or fractures, anatomical variants (deviated septum, concha bullosa) and extent of disease for surgical planning. It can also identify tumor involvement, osteomyelitis, and complications extending into the orbit or skull base.

A paranasal sinus CT scan is generally not painful. You lie still while brief X‑ray images are taken; the procedure usually takes only a few minutes. If IV contrast is used you may feel a short warm flushing, metallic taste, or mild stinging at the injection site. Some people have discomfort from lying still or mild claustrophobia, but the scan itself is painless.

A CT PNS (paranasal sinuses) typically costs: India ₹800–5,000 at private centres; UK residents get it free on the NHS, while private scans run about £100–£400; USA out‑of‑pocket fees vary widely, roughly $300–$2,500 (higher in hospitals or without insurance). Ask your healthcare provider or imaging centre for exact pricing, available discounts, and what is included.
