Advanced Radiology & Diagnostic Imaging Facility, a NABL & NABH-accredited diagnostic centre in Molecular Diagnostics and Therapy, is a place to go for CECT PNS. In the clinical setting, this may be needed to evaluate selected sinus abnormality/inflammatory changes, soft-tissue lesions, and inferred complications of the sinuses in a more detailed or extensive manner than possible with a simple unenhanced computed tomography (CT) scan.

About CECT PNS Sagittal

It is a specialized computed tomography scan of the paranasal sinuses (temporal bone) in which additional information can be obtained in the nasal sinuses and adjacent tissues, and these are indicated with special intravenous contrast. Air-filled pockets around the nose (maxillary, frontal, ethmoid, and sphenoid cavities). Side-on images of anatomical features and drainage pathways of the sinuses are sagittal images. Contrast enhancement can be used to evaluate selected inflammatory conditions and/or abnormal soft-tissue changes, masses, and suspected complications.

What is CECT PNS Sagittal?

The scan uses X-rays and computers to produce detailed images of the cross sections of the body. The injection of a contrast agent into the blood causes selected tissue, lesions, and areas of inflammation to be more visible. The sagittal plane is used with axial and coronal views to depict side views. If necessary for another clinical indication, there may be other image planes, or image reconstructions, that can be acquired to obtain a complete assessment. CT scan (without dye) is usually ordered for routine sinus evaluations. There is no contrast needed in the absence of any suspicion of disease in surrounding tissues, in selected masses, or perceived complications with a diagnosis, and this is the way in which CECT PNS employs contrast.

Common Reasons for CECT PNS Sagittal

• Complicated Sinusitis: Further tests of sinus infection if the infection has spread outside of the sinuses.
• Assessment normally involves, but is not limited to, abnormalities located in the sinuses and any adjoining soft tissue, which result in facial pain and swelling.
• Sinus Complications (Suspected): When clinically indicated, probing for possible spread of infection to nearby structures.
• Soft-Tissue Lesions: Masses or abnormal tissue of nasal cavity or paranasal sinuses.
• Assessment of orbital extension (eye socket) from sinus disease.
• Inflammatory changes: Evaluating select inflammatory changes of the sinuses and associated tissues.
• Abnormal Previous Imaging: Additional description of findings seen on previous CT, MRI, or other imaging studies.
• Postoperative Assessment: Evidence of the probability of recurrence of abnormalities; to investigate specific postoperative complications.
• Treatment Planning: An assessment of the site and role of particular sinus lesions and/or complicated disease.

Conditions Evaluated

Sinus Inflammation and Infection

As a general rule, when extension into other soft tissues is suspected, or if the condition is complicated, some inflammatory or infectious diseases of the paranasal sinuses may be an indication for a CECT. The findings are interpreted with the information gathered from clinical and examination findings.

Complicated Sinusitis

Contrast-enhanced computed tomography (CT) could be helpful in examining the distribution of disease and any changes in adjacent tissues in patients with suspected complicated sinusitis. Depending on the potential complication, additional imaging and/or emergent assessment may be needed.

Orbital Complications

Paranasal sinuses are close to the eye sockets. If the sinus infection is suspected to have involved the orbit (infection around the eye), contrast-enhanced computed tomography (CT) might be helpful in better understanding what has happened in the surrounding soft tissues of the eye and can assist in subsequent management.

Nasal Cavity and Sinus Masses

Contrast may be needed to aid in outlining soft tissue masses and abnormalities in the nasal cavity or paranasal sinuses. Depending on the results, other tests such as MRI or biopsy may be necessary.

Soft-Tissue Abnormalities

Computed tomography (CT) can evaluate the abnormal tissue surrounding the sinuses and how this tissue is related to any surrounding anatomical structures. May be of benefit in cases when the size of a suspected lesion is in doubt.

Extension into Adjacent Structures

Selected sinus disorders might be evaluated by imaging procedures for potential invasion of the sinus disorder into local skin and other contiguous anatomical structures. The particular scan covered depends on the clinical indication and protocol.

Anatomical Assessment

Sagittal reconstructions provide helpful supplementary information regarding the nasal cavity, sinus drainage, and related structures. These images may be combined with other planes to evaluate the complex anatomic structures or to evaluate abnormalities.

Why Choose Molecular Diagnostics and Therapy?

Molecular Diagnostics and Therapy is an NABL & NABH Accredited Diagnostic Centre that provides the modern and latest techniques of Molecular Nuclear Radiology, Molecular Nuclear Medicine, and Pathology treatment in a single center. We are experts in protocol suitability, choosing the right images, patient comfort, and reporting accuracy. Before the scan, the patient is given instructions on how to take the contrast and what their preparatory measures will be, as well as any precautions they should take.

Book Your CECT PNS Sagittal

If your doctor has suggested you have a CECT PNS Sagittal, please contact Molecular Diagnostics and Therapy to make an appointment. Bring your medication and old CT and/or MRI scans as well as previous ENT consultation notes and medical records (if available). Let the imaging staff know if you have a history of reaction to contrast dye, kidney disease, thyroid disease, any current medications, and/or the possibility of pregnancy before the imaging procedure.
