A CT scan, or computed tomography, is a medical imaging exam that uses X-rays to create detailed images of the sinuses and surrounding structures. This exam is particularly useful for detecting nasal polyps, chronic sinusitis, and other abnormalities that can affect your sinus health.
A CT scan therefore complements the nasal endoscopy that your doctor does in the clinic

What is a CT scan?
Your doctor may recommend a CT scan to assess the presence of nasal polyps, which are non-cancerous growths in the nose or sinuses.
The CT scan helps determine their size, location, and impact on your sinus health, which is essential for deciding on treatment, such as sinus surgery if necessary.
