A sinus CT scan is a non-invasive imaging technique that uses X-rays and computer technology to create detailed, 3D images of your sinuses and nasal passages. It provides a clearer view than standard X-rays and helps doctors diagnose chronic sinus issues, nasal blockages, infections, and structural abnormalities affecting breathing.
A sinus CT scan is typically recommended if you have:
1.) Chronic sinus infections (lasting 12 weeks or longer)
2.) Nasal congestion that doesn’t improve with treatment
3.) Facial pressure or headaches linked to sinus issues
4.) Nasal polyps or suspected growths in the sinuses
5.) A deviated septum or structural abnormalities affecting breathing
6.) Suspected fungal or bacterial sinus infections
The scan itself takes about 10 to 15 minutes, but you may spend 30 to 45 minutes total at the imaging center, including check-in and preparation.
Most sinus CT scans do not require contrast dye. However, if your doctor is evaluating tumors, vascular conditions, or severe infections, contrast may be used. If contrast is necessary, it will be administered through an IV, and you may need to fast for a few hours beforehand.
No, a CT scan is a painless, non-invasive study. You’ll lie comfortably on a table while the scanner takes images.
Some insurance plans require a doctor’s referral, while others do not. It is important to check with your doctor and your insurance benefits manager to determine if one is needed before scheduling.
Yes, sinus CT scans are safe and commonly used to diagnose sinus conditions. They use low-dose radiation, and our imaging specialists take every precaution to minimize exposure. If you are pregnant or have concerns about radiation, let your doctor know before scheduling.
You may be asked to avoid eating or drinking for a certain period of time before your scan, especially if contrast is recommended. Wear comfortable clothing and remove any metal objects like jewelry. Our team will review your medical history when you arrive for your appointment to ensure the proper preparation was followed before the study begins.
One of our board-certified, subspecialized radiologists will review your images, and develop a detailed report. The results are typically sent to your referring doctor within 1 – 2 days, and available in our patient portal within 5 – 7 days.
