CT PNS 1MM Cuts & Workshop Protocol Hyderabad | Focus Diagnostics

About CT PNS 1MM Cuts & Workshop Protocol

CT PNS refers to computed tomography of the paranasal sinuses. This imaging examination produces detailed cross-sectional images of the air-filled sinus cavities surrounding the nose. Thin-section imaging can help visualise sinus anatomy and identify abnormalities that may not be fully assessed using a routine physical examination.

The examination may be requested to evaluate the paranasal sinuses, nasal passages and surrounding bony structures. The precise imaging protocol depends on the referring doctor's requirements and the radiologist's assessment.

Why Is a CT PNS Scan Recommended?

A doctor may recommend a CT PNS scan when detailed imaging is required to investigate persistent sinus symptoms or assess the anatomy of the paranasal sinuses.

Clinical indications may include persistent or recurrent sinusitis, suspected sinus obstruction, evaluation of sinus anatomy before selected surgical procedures, and investigation of certain sinus-related abnormalities.

What Does CT PNS Evaluate?

• The frontal, maxillary, ethmoid and sphenoid sinuses.
• Sinus mucosal thickening and fluid accumulation.
• Possible obstruction of sinus drainage pathways.
• The bony walls and anatomical variations of the paranasal sinuses.
• Selected abnormalities involving the nasal cavity and surrounding structures.

The findings depend on the clinical indication, scan protocol and structures included in the examination.

What Are 1 mm CT Cuts?

Thin-section CT imaging uses narrow image slices to provide detailed anatomical information. A 1 mm reconstruction may help demonstrate small structures and support multiplanar image review when appropriate.

The actual acquisition and reconstruction settings are determined by the radiology protocol. The wording in the test name should not be interpreted as a guarantee of a specific technical protocol without confirmation from the diagnostic centre.

How Is a CT PNS Scan Performed?

The patient lies on the CT scanner table while images of the paranasal sinuses are acquired. The scanner uses X-rays to generate cross-sectional images, and the patient may be asked to remain still during image acquisition.

Many routine CT PNS examinations are performed without intravenous contrast, although the protocol depends on the clinical indication. Follow the instructions provided by the radiology team.

Preparation for CT PNS

• Follow the preparation instructions provided by the diagnostic centre.
• Inform the radiology team if you are pregnant or may be pregnant.
• Tell the team about previous imaging, relevant medical conditions and any requested contrast-related precautions.
• Bring previous sinus imaging and relevant medical reports, if available.
• Remove metal objects from the scanned area when instructed.

Preparation requirements vary depending on the prescribed imaging protocol. Confirm whether any special preparation is necessary before your appointment.

Does CT PNS Use Radiation?

Yes. CT imaging uses X-rays to produce detailed images. The radiology team selects an appropriate protocol based on the clinical indication and applies radiation optimisation principles.

Inform your healthcare provider if you are pregnant or may be pregnant so that the need for imaging can be assessed appropriately.

Understanding Your CT PNS Report

The report may describe sinus aeration, mucosal thickening, fluid levels, drainage pathways, anatomical variations and other relevant findings.

Imaging findings should be interpreted alongside symptoms and clinical examination. Not every abnormality seen on a scan necessarily explains a patient's symptoms, and the treating doctor determines whether further evaluation or treatment is needed.
