Sinus CT

A sinus CT scan is a fast, painless and noninvasive tool for evaluating sinus obstruction and is the best imaging technique for patients with acute or chronic sinusitis. The scan uses X-ray technology and advanced computer analysis to create detailed pictures of the paranasal sinus cavities, helping physicians assess acute or chronic sinusitis, analyze tumors and plan for medical procedures. It can potentially eliminate the need for exploratory surgery and surgical biopsy. At Washington Radiology, sinus CT scans are performed by an experienced CT technologist and interpreted by a board-certified radiologist. 


A sinus CT scan provides detailed images of the paranasal cavities, an important diagnostic tool when working with patients who suffer from acute or chronic sinusitis. The exam helps physicians identify and analyze obstructions and develop a treatment plan. In addition to pinpointing sinus inflammation, a CT sinus scan also can help detect cancer.

The exam takes no more than 15 to 30 minutes and there is no downtime. Radiation is not retained in the body after the exam and there are no immediate side effects.

No. It is painless and noninvasive. The technologist will position you comfortably on the table. You will need to lie still and hold your breath for a few seconds during the scan because any movement may distort the quality of the images.
