Contrast notes
Sinus CT is performed without IV contrast — bone and air clearly outline sinus mucosa on non-contrast images. Contrast is reserved for suspected tumor or complication.
Prep summary
Most patients don't need special prep beyond completing the MRI/CT safety screening and removing metal jewelry. Specific prep (fasting, contrast, medication timing) is confirmed at scheduling.

Plan for 15–20 minutes. You'll lie on the CT table while the scanner acquires images of the sinuses in under a minute. No preparation is required.
Results and report turnaround
Every study is interpreted by a board-certified radiologist — most by fellowship-trained sub-specialists in the relevant body system. Preliminary reads are typically available within a few hours, with the signed final report sent to your ordering provider the same business day.
You can also request a copy of the report and the imaging on disk for your own records or for a second opinion.
