CT PNS is a CT scan of paranasal sinus cavities. CT scan is also known as Computerized tomography. It uses special x-ray equipment that provides detailed and accurate results. It is a non-invasive reliable imaging technique to detect an obstruction or inflammation in the sinus. What is paranasal sinus?

2021年3月17日 · A PNS CT scan is an imaging test that helps check your paranasal sinuses, which are air-filled hollow spaces in the bones around your nasal cavity. A CT scan uses x-ray radiation and a computer to generate slices (cross-sectional images) of your internal organs, bones, blood vessels and soft tissues.

2024年6月28日 · In neoplastic, inflammatory and infectious disorders, a CT scan of the paranasal sinuses is performed to demonstrate bony erosions, osteolytic lesions, and calcifications. If neoplasia is suspected, the use of an intravenous contrast medium is indicated.

The CECT protocol for evaluation of suspected IFS can be modified by using split-bolus, single-phase CT as it provides an optimal soft tissue demonstration of sinonasal disease; extrasinus spread to orbit, and intracranial involvement along with simultaneous opacification of the internal carotid artery and cavernous sinus.

2021年1月1日 · Contrast enhanced computed tomography (CECT) has been the imaging method of choice in the pre-operative examination of patients who are candidates for functional endoscopic...

CT of the PNS is primarily used to: aid in the diagnosis of sinusitis. Examine sinuses that have fluid in them or thickened sinus membranes. detect the presence of infectious diseases. provide additional information on nasal cavity and sinus tumours. By …

2021年12月16日 · Aim: This study aims to evaluate the Paranasal sinus (PNS) pathologies on Contrast Enhanced Computerised Tomography (CECT) and to correlate CECT findings with eventual histopathological findings to evaluate diagnostic accuracy of the modality.

Primary pulmonary myxoid sarcoma (PPMS) is an extremely rare malignant mesenchymal tumor of the lung, with only less than 40 cases reported. We described a case of a...

2023年5月26日 · CT scan paranasal sinuses also known as CT scan PNS is a diagnostic tool used for evaluation and assessment of various diseases affecting the mucosa and bony cavities of paranasal sinuses. CT scan is the preferred imaging modality to identify various pathologies and conditions affecting paranasal sinus.
