CECT Nasopharynx - Axial
What is CECT Nasopharynx - Axial?
A CECT Nasopharynx - Axial test, also known as Contrast-Enhanced Computed Tomography of the nasopharynx, is a medical imaging technique. It uses special X-ray equipment, contrast material, and software to create cross-sectional images of the paranasal sinus cavities (respiratory part of the nasal cavity) and pharynx (mouth, throat, and esophagus). The three-dimensional images produced by the scan helps physicians and otolaryngologists to locate and diagnose symptoms like headaches, nosebleeds, nose blockage and numbness, and throat infections.
Increased exposure to x-rays during the procedure may cause damage to the cells in the body. However, in most cases, only a low level of radiation is used to avoid side effects. An abnormal scan test may indicate squamous cell carcinomas or nasopharyngeal lesions, sinusitis (infection of sinuses), and nasal obstruction.
Why is CECT Nasopharynx - Axial done?
- To diagnose pharyngitis / sore throat (inflammation of the pharynx) and laryngitis (inflammation of the larynx)
- To detect sinusitis (inflammation of the sinuses), tonsillitis (inflammation of the lymph nodes), epiglottitis (inflammation of the lid of larynx)
- To find out nasal obstruction and otitis media (earache with nasopharyngeal infection) and croup / laryngotracheobronchitis (viral infection which leads to infected airways passage)
