What would an MRI of my head show that a Sinus CT Scan and a Maxiofacial CT Scan didnt?

Quite a Lot: MRI is more helpful for soft tissue problems of blood vessels, inflammation, demyelination of brain tissue, and fluid collections. It seems you are undergoing a lot of tests, but without a clear diagnosis you can not be certain of the correct treatment. Ask your physician to explain the different treatments these tests will suggest. Tests are not useful, solely, because you have symptoms. ...Read more

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

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. ...Read more

Will a temporal or sinus CT scsn show issues with brain?

Will a temporal or sinus CT scsn show issues with brain?

Not very well: Ct techniques used to image the temporal bones or sinuses are tailored specifically to evaluate these areas. Only small portions of the brain are even included in the field of view. Also, the images are processed to give the best bony detail which makes the soft tissues difficult to evaluate. While an abnormality may be detected, these scans are not sufficient to evaluate the brain. ...Read more

My ENT said my sinus CT showed tiny dots in my sinus that looked they could turn into polyps. Can somebody explain this further?

Tiny dots: Hello, as an ENT physician I am not quite sure what the "tiny dots" are that he/she is actually referring to. I would assume it may be small lesions such as mucoceles or cysts that are commonly found in normal healthy sinuses. If I identify these lesions, I usually inform the patients that as long as they are benign in appearance and non-obstructive, we just observe these or just ignore them. ...Read more

How long does a sinus CT take?

Sinus CT: Sinus CTs take a couple of minutes to do. Most are done without contrast so you do not need an IV unless your doctor is looking for an enhancing mass, which I doubt in your case. You just need to hold still and do not move through the scanner (which is shaped like a doughnut). Good luck and feel better! ...Read more
