Diagnopein CT PNS (PLAIN WITH CONTRAST) Centre in Nashik

Importance and Placement of CT PNS with Contrast

A CT PNS with contrast plays an essential role in diagnosing complex sinus or nasal conditions. It identifies inflammation, blockages, cysts, or tumors in the sinus area. The scan is typically recommended for patients with symptoms like repeated sinus infections, nasal obstruction, headaches, or facial pain.

In terms of placement, the patient lies comfortably on a CT table, and the head is positioned to focus on the paranasal sinuses. A contrast agent (usually containing iodine) is injected intravenously before the second set of scans. This allows radiologists to compare plain and enhanced images for a clearer view of both bone and soft tissue structures.

Benefits of CT PNS (Plain with Contrast)

There are several key benefits of undergoing a CT PNS (Plain with Contrast) scan at Diagnopein, Nashik:

1. Detailed visualization: Offers precise imaging of the sinus cavities, nasal passages, and adjacent bone structures.

2. Dual assessment: The combination of plain and contrast imaging provides a complete picture for accurate diagnosis.

3. Non-invasive and quick: The entire procedure usually takes less than 15 minutes.

4. Early detection: Identifies sinus blockages, infections, and abnormal growths early, supporting timely treatment.

5. Helps surgical planning: Often used for pre-surgical mapping, especially in functional endoscopic sinus surgeries (FESS).

How CT PNS (Plain with Contrast) Testing Is Done

The CT PNS with contrast test is conducted by trained radiology professionals at Diagnopein in a safe and comfortable environment.

Steps involved:

1. The patient is asked to lie still on the CT table with the head positioned inside the scanning ring.

2. A set of plain (non-contrast) images is captured first.

3. A contrast dye is then injected, usually through a vein in the arm.

4. The second scan captures contrast-enhanced images showing fine details of the sinus mucosa, blood vessels, and tissues.

5. After the scan, images are processed and interpreted by a radiologist to create a comprehensive diagnostic report.

Precautions: Patients with allergies to iodine or kidney disease should inform the radiologist before the test. Minimal radiation is used, making it safe under medical supervision.

Parameters and Technical Details

Below are the standard technical parameters followed during the CT PNS (Plain with Contrast) scan at Diagnopein, Nashik:

1. Scan area: Paranasal sinuses, nasal cavity, and adjacent facial bones

2. Slice thickness: 0.5 to 1.25 mm for detailed cross-sectional images

3. Technique: Helical/axial CT scanning with plain and contrast phases

4. Contrast medium: Non-ionic iodine-based dye

5. Scan duration: 5 to 10 minutes (depending on patient’s condition)

6. Report delivery: Within a few hours

These parameters ensure accuracy and clarity in identifying abnormalities or infections within the sinus structure.
