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

Had CT scan done of my sinuses today and she showed me my sinues and top of head and said no lesions. Would this show cerebellum?

Had CT scan done of my sinuses today and she showed me my sinues and top of head and said no lesions. Would this show cerebellum?

Probably not: Most dedicated sinus CT scans focus specifically on the sinuses, which are located around the nose in the front of the head. The cerebellum is in the back of the head. Also, the images on a sinus CT are produced in such a way as to optimize appearance of the bony structures, which makes it hard to see the parts of the brain that happen to show up in the images. ...Read more

Saw my ENT after CT scan. She showed me my sinuses and then she showed me a round solid grey circle. Was that top of head? She said it looked fine to.

Saw my ENT after CT scan. She showed me my sinuses and then she showed me a round solid grey circle. Was that top of head? She said it looked fine to.

No: There are basically three densities in the CAT scan of the paranasal sinuses. Black is air, dense white is bone and grey is soft tissue. A round grey circle could have been the orbit (eye). It was not the top of the head which would have been dense white. After viewing the CAT scan with your ENT doctor, you should have walked away with a lot more information. ...Read more

Would a CT scan see an infection, more specifically a dental infection?

Sinus dx nl ct: It is hard to have sinus disease with a normal cat scan. You may have gotten a reading of benign findings. Basically this means it is negative for any masses or lesions.

Within a matter of 4 years I had 2 brain CT scans and 1 sinus CT scan, I am worried about developing cancer. Should I be alarmed with having 3 in 4 yr?

See below: Radiation exposure to head can lead to cancer and it is dose related. Children who have received high dose radiation therapy for head and neck cancer can develop an unrelated form of cancer later on in life. The dosage from ct scan is much lower and the risk is very small. There is no need to be alarmed, do try to avoid more ct scans unless it is absolutely necessary. Mri scan has no radiation. ...Read more
