When you get sinus ct scan are they looking at the whole head or just your sinuses ?

Sinus CT: CT scans are directed to the specific anatomy that your doctor is interested in. A sinus CT is focused and optimized to examine your nasal and sinus cavities. Although surrounding structures are viewed at times, including other parts of your head, the radiologist will adjust the window settings for the specific tissue of interest. Also some tissues image better with contrast. Hope this helps.
