A CT Sinus scan is a fast, painless imaging test that creates detailed pictures of the sinus cavities to assess inflammation, infection, blockages, and structural abnormalities. It is the most reliable imaging method for diagnosing sinusitis. At Advicon Imaging, Medicare-eligible CT Sinus scans are fully bulk-billed.

A CT Sinus scan uses specialised X‑ray technology to produce highly detailed cross-sectional images of the paranasal sinuses—the air-filled spaces in the bones of the face surrounding the nasal cavity. Unlike standard X-rays, CT provides superior clarity of soft tissue, bone structures, and sinus drainage pathways, making it the gold standard for evaluating sinus disease.
Doctors commonly request a CT Sinus scan for patients experiencing chronic nasal congestion, facial pain or pressure, recurrent sinus infections, reduced sense of smell, or when symptoms do not respond to treatment. It is also essential for pre-surgical planning, particularly before endoscopic sinus surgery, as it provides precise anatomical detail.
During the scan, you will lie on a CT table that slides into a doughnut-shaped scanner. The scan is quick and painless, typically taking only a few minutes. Most CT Sinus studies do **not** require contrast injection. However, in special circumstances—such as suspected tumours or complications—your doctor may request contrast.
At Advicon Imaging, we use advanced CT technology to minimise radiation exposure while maintaining excellent image quality. All Medicare-eligible CT Sinus examinations are fully bulk-billed.
It is a CT scan that produces detailed images of the sinuses to diagnose inflammation, infection, blockages, and structural abnormalities.
Reasons include chronic sinusitis, facial pain, nasal obstruction, recurrent infections, or preparation for sinus surgery.
Usually, no preparation is required.
No. CT Sinus scanning is completely painless and non-invasive.
Yes, but the dose is low and optimised using modern CT technology.
Most patients will not. If contrast is requested, you may feel a brief warm sensation during injection.
The scan itself takes 2–5 minutes. The entire appointment is usually less than 15 minutes.
Yes. You may return to normal activities immediately.
Typically within 24–48 hours, with urgent reports prioritised.
