CT Scan PNS Axial Contrast, in Visit Clinic

A CT scan with contrast for PNS is a computed tomography study of the paranasal sinuses performed after intravenous iodinated contrast. It produces detailed cross‑sectional images that better define mucosal disease, sinus opacification, inflammatory complications, vascularity or masses, and bone involvement—useful for detecting tumors or complex infection and for surgical planning. Contrast is avoided in severe allergy or significant kidney dysfunction.

PNS in a CT scan stands for paranasal sinuses. A CT PNS provides detailed bone and air-space images of the frontal, maxillary, ethmoid and sphenoid sinuses, used to diagnose sinusitis, polyps, anatomical variants, fractures, infections or tumors, and to plan surgery. It shows mucosal thickening, fluid levels, bone erosion and obstruction of sinus drainage pathways.

A paranasal sinuses (PNS) CT scan is generally painless and noninvasive. You lie on a table while images are taken; you may feel minor discomfort from lying still or anxiety/claustrophobia. If intravenous contrast is used, you might notice a brief sting, metallic taste, or warm flushing. Serious pain or complications are rare; tell staff about allergies, kidney problems, or pregnancy beforehand.

A CT scan of the paranasal sinuses typically takes very little time: the actual image acquisition is usually 1–5 minutes, with positioning and set‑up adding another 5–10 minutes. Most appointments are completed in 15–30 minutes. If intravenous contrast is required, allow extra time for IV insertion and delayed imaging, extending the visit to around 30–60 minutes.

A CT PNS (paranasal sinuses) typically costs: India ~₹800–₹4,000 at private imaging centers; UK—free on the NHS or ~£150–£500 privately; USA—about $300–$3,000 depending on hospital, outpatient clinic, and whether contrast is used. Prices vary by location, facility type, and any additional radiologist/reporting fees; always check local imaging centers for exact charges.

No fasting is needed for a routine CT PNS without contrast. If iodinated contrast is planned, you may be asked to fast about 4–6 hours and report medications, diabetes, or kidney disease. If sedation or general anesthesia is required, follow stricter fasting rules. You may usually drink clear fluids unless told otherwise. Remove jewelry and inform staff if pregnant.
