A CT PNS Axial and Coronal view is a type of medical imaging test that provides detailed cross-sectional images of the sinuses – the small, air-filled cavities within the bones of the face and skull. These images are helpful in diagnosing a wide range of sinus and nasal conditions, including sinusitis, nasal polyps, and structural problems such as a deviated septum.
The CT scan utilizes x-ray radiation and computer technology to produce cross-sectional images of internal organs, bones, blood vessels, and soft tissues. These PNS CT Scan images can be viewed in either axial or coronal positions, with the former providing a top-to-bottom view of the sinus cavities and the latter offering a front-to-back perspective. To obtain a CT PNS coronal view, the patient must lie face down on the scanning table with their hard palate perpendicular to the gantry, while an CT PNS axial view requires the person to keep their hard palate perpendicular to the scanning table. If a patient is unable to lie prone for a coronal scan, a computer-generated reconstructed coronal view can be obtained from axial sections.
Before the CT scan, it's crucial to follow specific instructions to ensure clear, accurate images:
Fasting : Usually, fasting isn't necessary before a CT PNS scan. However, if the procedure involves a contrast dye, you might be asked to fast for several hours beforehand.
Allergies : If you have an allergy to iodine or contrast material, inform your doctor or radiologist. Contrast material can cause an allergic reaction in some people.
Medication : Continue taking regular medications unless instructed otherwise by your doctor. If you're diabetic or have certain heart conditions and are on medication, your doctor may provide special instructions.
Pregnancy : It's crucial to inform the doctor or radiologist if there's any chance you could be pregnant.
The degree of the paranasal sinuses is assessed through a CT scan. To identify vascular tumors, PNS Axial and Coronal scanning with Contrast is performed. Contrast-enhanced CT is especially beneficial in evaluating neoplastic, chronic, and inflammatory conditions.
Axial and Coronal views are different planes radiologists use to assess anatomy and pathology from various angles. The axial plane divides the body into top and bottom halves, while the coronal plane divides it into front and back halves.
CT PNS can detect various conditions, such as sinusitis, nasal polyps, tumors, and structural abnormalities like a deviated septum. It can also help identify complications of sinusitis like abscesses or bone infection.
The scan itself generally takes about 15-20 minutes. However, you should plan on being at the imaging center for about an hour to allow time for preparation and follow-up.
The CT scan of the paranasal sinus(PNS) is a quick, safe, and painless procedure that offers more detailed information compared to traditional X-rays.
