CT PNS AXIAL / CORONAL VIEWS

CT PNS (Paranasal Sinuses) Axial/Coronal Views Overview

Computed Tomography (CT) scanning of the paranasal sinuses is a specific diagnostic examination aimed at examining the sinuses along with their adjacent anatomical structures. This procedure employs X-rays integrated with computer imaging to obtain images of the sinuses in both the axial(horizontal) and coronal (vertical) planes. 

Each CT scan of the patient is reviewed for information about the surrounding structures that may include tumours, infection or fractures of facial bones and other pathologic processes that affect the sinuses. 

What is CT PNS Axial/Coronal Views? 

CT PNS is a more detailed examination of the sinuses using an X-ray that is taken in a non-invasive way. it can be done in a CT Scanner which is a huge double-sided machine consisting of an X-ray within and sensors. The x-ray Around the patient capturing multiple images from different viewpoints. Implementation of the data through a computer generates detailed cross-sectional images of the sinuses in both horizontal and vertical planes. 

Types of CT PNS scans: Axial/Coronal Views 

The types of CT PNS scans are as follows: 

• Without contrast PNS CT: This is the basic scan that is conducted to check the sinuses and their surrounding areas. 
• With contrast-enhanced PNS CT: This scan uses dye injection to improve certain structures within the sinuses and surrounding areas. 
• Thin-slice PNS CT: Slices of the sinuses used are thinner, making images more detailed. 

List of Parameters Considered During the CT PNS Axial/Coronal Views

The factors listed below will be analyzed during the scan: 

• Cavities of the sinuses: Their thickness, shape, and size as well as the mucosa layers. 
• Walls of the sinuses: Defects, radiolucency or fracture lines, and their density or opacity. 
• Passages of the nose: The degree of their aperture and configuration.  
• The orbits, the brain and the rest of the soft parts of the head: The rest of the structures. 

Reasons for Taking a CT PNS Axial/Coronal Views

A CT PNS scan might be advised for these conditions or symptoms:  

• Sinusitis (acute or chronic) 
• Nasal polyps 
• Tumours or cysts in the sinuses 
• Trauma or injuries to the face 
• Hyposmia or epistaxis 
• Headaches or painful sensations in the face  

When and Who Should Consider a CT PNS Axial/Coronal Views? 

A CT PNS scan might be needed for patients who have:  

• Chronic sinusitis or recurrent sinus infections.  
• Nasal obstruction, facial discomfort, and/or head pain.  
• Facial fractures or other forms of facial trauma.  
• Smell impairment or epistaxis (bleeding from the nose).  
• Bone surgery assessment before a sinus operation.  
• Follow-up of patients suffering from sinus disease: fungal sinusitis or tumour malignancy. 

All patients, including young children, scheduled for the exam, are recognizable for these criteria.  

Benefits of Taking the Test

The advantages derived from taking a CT PNS scan include:  

• Correct identification of diseases and conditions of the sinuses. 
• Assessment of the sinuses and other adjoining regions. 
• Assistance in surgical procedures and other interventions involving the sinuses. 
• Evaluation and reviewing of diseases and conditions of the sinuses.  

Illnesses Diagnosed with CT PNS Axial/Coronal Views

A CT PNS scan can show a wide variety of conditions such as:  

• Sinusitis (acute or chronic) 
• Polyposis of the nose 
• Tumours or cysts of the sinuses 
• Fungal sinusitis 
• Fracture or trauma of the sinus 
• Obstruction or Stenosis of the nose  

Preparing for CT PNS Axial/Coronal Views

Before the scan patients must:  

Not wear any jewelry or glasses. 

• Put on loose and comfortable clothing. 
• Take out dentures or any implants. 
• Come in early to complete necessary paperwork. 

Pre-requisites: There are no specific suggestions for the test, but people may want to suggest to: 

1. Refrain from eating or drinking anything for some time prior to the examination 
2.  Do not take certain medications that may alter the outcome of the examination results  

Best Time to Take the CT PNS Axial/Coronal Views: The optimal time for taking the test is usually during the morning period, when the sinuses are normally empty. However, all tests can be done at any time of the day.  

Eligibility: The test is generally acceptable for all age groups of patients, but there may be some exceptions like: 

1. Women in pregnancy or lactation 

2. Patients with some medical conditions like kidney ailment or some allergies 

3. Patients with some surgical implants like metallic parts or some electronic devices like pacemaker.  

Procedure for Taking a CT PNS Axial/Coronal Views  

The steps of the procedure to be undertaken usually take from 15 to 30 minutes and are the following. 

1. The patient is placed on the CT table, often supine. 

2. The scanner rotates around the patient and the scanner is rotated around the patient to take pictures from different perspectives. 

3. The patient must stay still during the time of the scan and most likely will need to hold their breath. 

4. The scans will be taken in the axial and coronal planes. 

Caution before Patients Take the Test 

Patients are recommended to notify their physician or technician regarding: 

• Any allergies to or sensitivity towards the contrast dye used in the procedure.  
• Any other medical condition that you may have, or any implants that patients may have.  
• Any other worries or anxiousness that might be experienced in relation to the test.
