A NABL / NABH accredited diagnostic centre, Molecular Diagnostics and Therapy provides a range of Radiology / diagnostic imaging services, amongst which NCCT PNS (AX./COR/SAG) is one. The non-contrast CT scan of the paranasal sinuses is performed, allowing assessment of the nasal cavity and paranasal sinuses' gross anatomy, sinus inflammation, and nasal obstruction in all planes (axial, coronal, and sagittal). CT can be used to look at the structures of the nose and paranasal sinuses in great detail.

About NCCT PNS (AX./COR/SAG)

NCCT PNS (AX./COR/SAG) is the optimal study of the paranasal sinuses and other facial bones. Uses one or several pictures of the body in various planes of space. There are 3 planes in space, which are called axial, coronal, and sagittal. Paranasal sinuses are a group of air-filled spaces located in the facial bones around the nose; the paranasal sinuses consist of the maxillary sinuses, frontal sinuses, ethmoid sinuses, and sphenoid sinuses (or sinuses of the crania). CT scan of the paranasal sinuses can be performed in axial, coronal, and sagittal slices and may reveal shortcomings in the nose such as nasal obstruction and sinus inflammation. A scan may also be helpful when planning for surgery. NCCT PNS (AX./COR/SAG) might be used to investigate several health issues.

What is NCCT PNS (AX./COR/SAG)?

CT scanning involves the use of X-rays and computer technology to generate images of the body that are made up of cross sections. CT scanning is a quick and painless test that provides detailed, high-quality X-rays needed for the doctor to make a proper diagnosis. Non-contrast-enhanced computed tomography (CT scan) is a type of computed tomography (CT) scan that does not use a contrast material.

• Axial (AX) View: This view provides horizontal cross-sectional images of the nasal cavity and sinuses.
• Coronal (COR) View: This view provides front-oriented images, facilitating the assessment of sinus cavities, drainage pathways, and adjacent structures.
• Sagittal (SAG) View: This view provides side-oriented images, offering additional information on sinus anatomy and associated structures.

These views enable the radiologist to assess the opacification of the sinuses, thickness of the mucosa, the bony boundaries, and anatomical variations. The most common use of the test is to determine the anatomy of the sinuses and as a clinical aid in making decisions.

Common Reasons for NCCT PNS (AX./COR/SAG)

• Chronic Sinusitis: To diagnose, treat, or follow up on chronic or recurrent sinusitis.
• Nasal Obstruction: To determine the structural abnormalities that are associated with nasal obstruction.
• Facial Pain or Pressure: To determine if there is possible sinus involvement in patients with facial pain/pressure, when indicated.
• Recurrent Sinus Infections: To look at the sinus anatomy and the severity of the sinus infection.
• Mucosal Thickening: To see if the lining of the sinus is swollen and if there are abnormalities.
• Deviated Nasal Septum: To observe the deviation of the nasal septum and its effect on the nasal cavity.
• Sinus Drainage Obstruction: To assess if the sinus drainage pathways are clear.
• Anatomical Variations: To identify some selected anatomical variations that are of importance.
• Preoperative Assessment: Preoperative detailed imaging for selected Endoscopic sinus surgeries.
• Abnormal Previous Imaging: Further imaging of abnormalities found on previous imaging studies.

Conditions Evaluated

Chronic and Recurrent Sinusitis

Chronic/sinusitis can be diagnosed on a computed tomography (CT) scan, which can show thick mucus lining in the sinus and different levels of opacification. The results are interpreted based on a patient's symptoms to diagnose the disease.

Maxillary Sinus Abnormalities

Maxillary sinuses lie beneath the eyes on the sides of the nose in the cheekbone. Computed tomography (CT) can be used to see if there are any thickened mucous membranes or any extra fluid in the maxillary sinuses.

Frontal Sinus Abnormalities

The frontal sinuses are located above the eyes. CT scans can detect irregularities in the development of the frontal sinuses.

Ethmoid Sinus Abnormalities

The ethmoid sinuses are a set of tiny air cells in the deep part of the nasal cavity between the eyes. Abnormalities in the ethmoid sinuses can be detected by a CT scan.

Sphenoid Sinus Abnormalities

The sphenoid sinuses are within the skull behind the nose. CT scans can provide an identification of any abnormalities within the sphenoid sinus area.

Deviated Nasal Septum

A deviated nasal septum is a condition in which the wall between the two nasal passages is crooked. CT scans can detect a deviated nasal septum.

Nasal Polyps and Sinus Opacification

CT scans can detect abnormal soft tissue in the nasal cavity and sinuses, which can be caused by nasal polyps or sinus inflammation. An endoscopic examination of the nasal cavity may also be needed to confirm the diagnosis.

Sinus Drainage Pathway Abnormalities

CT scans can detect abnormalities in the drainage pathways of the sinuses. These pathways are made of nasal passages, bones, and muscles that allow mucus to drain from the sinuses. Obstruction in these pathways can lead to sinus infection or inflammation. Abnormalities in these pathways can be detected using axial, coronal, and sagittal CT scans.

Anatomical Variations of the Nasal Cavity

A CT scan can detect variations in the anatomy of the nasal cavity, such as the shape and size of the nasal passages and the septum. These variations can be classified as normal findings in certain cases.

Preoperative Sinus Assessment

CT scans can help evaluate the anatomy of the sinuses before surgery. This is especially important for surgeries to treat chronic sinusitis. The CT scan provides a detailed view of the sinuses.
