About the Scan- Sinus CT Scan

SMIL offers a sinus CT scan which gives our radiologists clearer images of the sinuses making it easier to identify problems.

A sinus CT scan shows a patient’s paranasal sinus cavities. The paranasal sinuses are hollow, air-filled spaces located within the bones of the face and surrounding the nasal cavity, a system of air channels connecting the nose with the back of the throat. There are four pairs of sinuses, each connected to the nasal cavity by small openings.

A sinus CT scan is primarily used to detect the presence of inflammatory disease and help diagnose sinusitis. A sinus scan can also identify nasal and sinus tumors, and evaluate sinuses that are filled with fluid or thickened sinus membranes.
