A computed tomography (CT) scan of the sinuses provides detailed images of the nasal passages and surrounding bony structures. The diagnostic imaging procedure utilizes X-rays and computer technology to create cross-sectional views, allowing visualization of sinus cavities, nasal septum, turbinates, and adjacent anatomical regions. For example, the scan can reveal the presence of inflammation, fluid accumulation, or structural abnormalities within the sinuses.
The examination holds significant importance in diagnosing various sinus-related conditions and guiding appropriate medical or surgical interventions. Its benefits include accurate identification of sinusitis, nasal polyps, tumors, and other anatomical variations that may contribute to sinus problems. Historically, sinus imaging relied on conventional X-rays, which offered limited detail compared to the enhanced resolution provided by CT scans.
