Getting CT scan for sinuses done in two weeks. Have constant congestion, loss of smell/taste. Issues swallowing. Could scan show issues swallowing?

Getting CT scan for sinuses done in two weeks. Have constant congestion, loss of smell/taste. Issues swallowing. Could scan show issues swallowing?

No: A CT of the sinuses is a very focused study, and while it does show the back of the throat, tonsils, adenoids, this is all stuff the doctor can see just by looking in your mouth so the CT adds nothing to the evaluation for swallowing. It will get some fantastic pictures of your sinuses though and is primarily used to determine if surgery or balloon sinuplasty may be helpful. ...Read more

What structures will a CT scan of sinuses show that the in-office scope examination does not? (like, where are nasal turbinates?)

Hard, firm, enlarged painless lymph node behind ear for 9 months. ENT wants to do a CT scan of sinuses. What's he looking for?

Lymph node: Lymph nodes in that region are in the lymphatic drainage path of parts of the scalp, posterior neck, and ear, so would not necessarily be enlarged from sinus disease. Your best bet is to ask the ENT, maybe they are looking for something else. A sinus CT would not be adequate to evaluate for neck adenopathy ...Read more

Had a CT scan of sinuses and found a legion behind my left ear displacing my carotid artery .caused sever pain in left ear and jaw what caused it ?

Skull base lesion: Without reviewing the scan, it is impossible to offer any differential diagnosis. It is also very likely that this may be an incidental finding, unrelated to your symptoms. The best source of information regarding the findings on the scan is the doctor who prescribed the scan. You will need an ENT consult. ...Read more

Whats the difference between a CT scan of the sinuses and a maxillofacial CT with contrast? Why would i need both?

Whats the difference between a CT scan of the sinuses and a maxillofacial CT with contrast? Why would i need both?

Not sure: If a physician is trying to determine if you have sinusitis, a cat scan without contrast is all you need. However, if your physician is concerned about something else such as a vascular anomaly or unusual growth in the maxillo-facial region, the radiologist may need to use contrast. Ask the doctor or radiologist to explain why both are needed. What is the diagnosis he wants to make? ...Read more

CT scan The frontal sinuses are well-developed. There is mild mucosal thickening involving the inferior aspect of the bilateral frontal sinuses.


CT  scan 
The frontal sinuses are well-developed. There is mild mucosal thickening involving the inferior aspect of the bilateral frontal sinuses.

What's the question?: You have given us a statement, not a question. I assume you want to know what the radiological diagnosis means. In my experience, when a radiologist states mild mucosal thickening in any sinus, it is probably not of much clinical significance. Are you symptomatic, are other sinuses involved, do you have headaches, and finally are you ill? We need to know these things to help you. ...Read more

Is image guided sinus surgery like having another CT scan of head/sinuses? Should one worry about commulative radiological exposure?

Yes and no: Image guided sinus surgery allows your surgeon to more accurately identify where they are working in an effort to reduce the chance of surgical injury and to assure that the sinus issues you suffer from are treated as effectively as possible. This does require additional radiation exposure for the scans, something that one should keep to a minimum. For many, benefits outweigh the risk. ...Read more

Ct Scan (Definition)

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
