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

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

Does a sinus CT show the eustachain tubes? Or does a CT of the temporal bones do a better job of this?

Both do: Both ct and MRI can view the eustachian tube if the cuts or slices are made thin enough. Neither can assess the functional aspects of the tube, only determine whether it appears normal or has a growth or mass in it our touching it. ...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

What is the definition or description of: sinus ct?

Sinus CT scan: A sinus ct (also called "cat" scan) is a quick and painless way of making high-resolution x-ray images of your sinus cavities. Doctors order this if they suspect sinus inflammation/infection or possible masses causing nasal or facial symptoms such as nasal blockage, bleeding, pain or discharge. Radiation is involved, so frequent exams are not recommended.

Super bad sinus pain and sinus CT "showed nothing" how an this be! And why am I still having pain?

Look for other cause: Problem for otolaryngologists are patients who present with recurrent, persistent sinus pain out of proportion to findings on physical exam. Patients experienced documented acute sinusitis in past often present new similar symptoms, lack objective evidence of new active sinus infection. These patients may or may not be experiencing an upper respiratory tract infection/nasal drip. Remain vigilant. ...Read more

How common is an endoscopy exam of the sinus and nasal passages? Are sinus CT scans better? When would you use one or the other?

Endoscopy: Endoscopy of the nose and sinuses occurs daily in an ent's office.

When is it better to get a sinus CT or a nasal endoscopy exam? Does one reveal more information? Are they used for different purposes?

Sinus exam: Unless you've had sinus surgery, the maxillary sinus openings are somewhat difficult to see with a scope. We can usually see the sphenoid sinus openings, but the remainder are not easily visualized routinely. Further, being able to see inside the sinuses is likewise not possible. Endoscopy helps us see polyps, infection, crusts, etc. Ct shows us what's in the sinuses. They're complimentary. ...Read more

Could still be sinus: Try the "modified valsalva maneuver" to see if there is a sinus component to the pain. Hold your nose and blow and pop your ears like you would on an airplane. If there is brief relief of the pain, it is sinus. If it makes it worse, it may be migraine ...Read more

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

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
