Is orbital CT scan and CT scan sinus the same?

Is orbital CT scan and CT scan sinus the same?

Not quite: The CT of the sinuses focuses in on the sinuses (though the radiation goes through the entire skull) and generally covers the entire set of sinuses (sphenoid, maxillary, frontal, ethmoid). The orbital CT will cover the eye sockets (and those pictures are zoomed in). While the sinuses lies behind the eyes (& so they overlap), the focus & coverage of these scans are slightly different. ...Read more

Can ent dr see if u have etd by checking ears or only thru a ct scan of sinus and ears?

ETD?: Eustachian tube dysfunction? Diagnosis can often by made by interview alone as symptoms/clinical course are typical. Aseptic swelling of the middle ear compartment (seen on ear exam) is supportive. CT scan will not help. If severe, and optimized treatment strategies for allergic or non-allergic rhinitis, gastric reflux, etc fail; then ENT will sometimes place ear tubes. ...Read more

Got a mucus retention cyst in sinus CT scan blocking sinus partially.What are the treatments to remove it or dissolve it?Suffering from post nasal dip

Not necessary to: Remove a mucous retention cyst is not necessarily the cause of your sinus problems. I take ct scans all day and we see a lot of mucous retention cysts with little correlation to symptoms. If you are going to have it out just know that your symptoms will probably not improve . Many university radiologists that read scans will advise against treatment because of the high reoccurrence rate ...Read more

Had CT scan for sinus/ear.Ent said it's clear.I looked at report it said I have a protuberant cavernous carotid artery covered by bone.What that mean?

Large vessel: The carotid arteries travel through the cavernous sinus which is a venous drainage system covered in part by bone. I think that they are pointing out that the cavernous carotid artery is confined in bone. If the artery breaks through the bone, it is said to be dehiscent--this can lead to big nose bleeds. ...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
