Sinus Ct Scan Radiation
Mini sinus Ct scan 3/17 tooth mini Ct scan 1 side 6/17 & again one week later is it too much radiation if I now have a regular Ct scan of face/neck?
Shouldn't be an issue: Overall this shouldn't be an issue exposure wise and these scans are to aid in diagnosis and unfortunately nothing can provide the same info that doesn't have some exposure to it.See 1 more doctor answer
In anatomy, a sinus is a cavity within a bone or other tissue. Most commonly found in the bones of the face and connecting with the nasal cavities. Sinus (anatomy), description of the general term paranasal sinuses, air cavities in the cranial bones, especially those near the nose, including: the maxillary sinuses, also called the maxillary antra and the largest of the ...Read more
Had a sinus CT scan for a deviated septum/chronic sinusitis. Now I'm worried about cancer from the radiation. Is it unlikely?
Very unlikely: While many studies have recently been published about radiation exposure & risk for cancer, the main concern is from repeated x-rays, not the occasional one. The media has also pointed out that it's important to go to reputable facilities that check their equipment regularly to insure appropriate dose is used. But in general, your risk for cancer from sinus ct scan is very unlikely.See 3 more doctor answers
Yes,: A sinus CT should cover the sphenoid bone.
Not likely: This is only usually confirmed py the pathologist. Often, we can tell at the time of the surgery which is most likely.See 1 more doctor answer
Probably the: Normal expected air, which appears black on ct, surrounded by mucosal thickening, which appears grey on ct. Bone is white or a lighter grey. Without the images, it is impossible to guarantee the assumptions above, but mucosal thickening is very common.
Possibly: One can have a normal looking ct with sinusitis, and abnormal ct with mild or no cold symptoms, it depends on how long things ahve been going on.
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. When you have a negative cr scan and nasal issues it is time to look elsewhere for abnormalities. I would check your allergies see an ENT or allergist and get worked up for this. Good luck and feel better!
It means: That there are no significant abnormalities, the scan is essentially normal.
Deviated septum: CT scans take cuts through part of the septum so it is possible that a septal deviation could be missed. Have your nose evaluated by a board certified otolaryngologist.See 2 more doctor answers
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.

What to do if I had a sinus CT scan. I have received the report. Can anyone help me understand the findings?
CT: You can speak with your doctor about the results. If you have a specific question, you can post it on HealthTap. Or, you can send a message to a HealthTap doc for more detail.
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.See 1 more doctor answer
Can a person have a clear sinus CT scan but still have sinus infection. I have had sinus infection symptoms for 7 months and clear sinus CT scan.
Not too likely: Sometimes things are missed. Problems with the osteomeatal complex are sometimes overlooked on ct. Best to have an ENT have a look.
Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! The image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more
Ct scan uses data from a beam of xrays and reconstructs a cross sectional image of your body. It is a high dose of xrays and used only when the benefits outweigh the risk. Cancer risk is 1 in 500 in children. Also using iodinated contrast might cause transient renal failure in about 5% of patients. (contrast induced nepropathy) most do not explain this to the patient as ...Read more
