A CT scan of the paranasal sinuses (PNS) uses X-rays to create detailed cross-sectional images. Axial images are horizontal slices, coronal images are frontal views, and sagittal images are side-to-side slices. Together they show sinus anatomy, inflammation, polyps, obstruction, or bone fractures, aiding diagnosis and surgical planning. It is quick and widely used.

A PNS CT scan is a computed tomography study of the paranasal sinuses that produces detailed cross-sectional images of sinus air spaces, bony anatomy and adjacent structures. It evaluates sinusitis, polyps, fractures, tumors and anatomical variants, guides medical or surgical planning, and detects mucosal thickening or fluid levels. It typically uses thin-slice, high-resolution images and is often done without contrast.

A sagittal CT scan is a computed tomography image reconstructed or acquired in the sagittal plane, which divides the body into left and right halves. It provides side‑view slices useful for evaluating spine alignment, vertebral fractures, sinuses, brain midline, joints and certain soft‑tissue or bone abnormalities. Sagittal reconstructions are commonly created from axial CT data to clarify anatomy and guide treatment.

CT PNS (paranasal sinuses) scan costs vary widely. In India private centers typically charge about ₹600–₹4,000. In the US prices range roughly $200–$3,000 depending on insurance, facility and contrast use. In the UK it’s free on the NHS but private scans commonly cost about £100–£400. Final cost depends on location, contrast, centre type and reporting fees.

A paranasal sinus (PNS) CT scan is generally painless. You lie still while X‑rays are taken; only minor discomfort may come from holding a position or anxiety. If intravenous contrast is used, you might feel a brief warm sensation, metallic taste, or mild sting at the injection site. Serious complications are rare—inform staff about allergies, pregnancy, or claustrophobia beforehand.

Axial (transverse) plane slices the body horizontally into superior (top) and inferior (bottom) parts, commonly used in CT/MRI. Coronal (frontal) plane divides the body into anterior (front) and posterior (back) sections. Sagittal plane splits the body into left and right halves; a midsagittal plane cuts at the midline, while parasagittal sections are off-center.
