A computed tomography (CT) scan of the paranasal sinuses uses X-rays to create detailed images of the air-filled spaces around the nose. This diagnostic imaging technique visualizes the bony structures, soft tissues, and any potential abnormalities within the sinus cavities. For example, the presence of thickened sinus lining, fluid accumulation, or bony erosion would be readily apparent on the images generated.
The clinical value of this imaging lies in its ability to assist in the diagnosis and management of various sinus-related conditions. Identifying the extent and nature of sinus disease aids in determining the appropriate course of treatment, whether it be medical management with antibiotics or surgical intervention. Historically, sinus imaging was limited to conventional X-rays, but CT scans offer superior anatomical detail and diagnostic accuracy, leading to more effective patient care.
