NCCT means a Non - Contrast CT Scan or a Plain CT PNS (Para-Nasal Sinuses). It is the gold standard investigation for diagnosing Sinus related problems.

Contrast injection is only used in special cases.

Newer CT Scan machines have a higher radiation exposure, but at the same time are able to give higher resolution scanning which is necessary to see the wafer thin bony partitions of the sinuses. They can also scan in multiple planes and are very quick, requiring just a couple of minutes for a scan. 

The amount of X-ray radiation exposure can be reduced by reducing the resolution if such High Resolution (HRCT) if it is not required in your case.

Hi, I have just had my second scan for sinitus, first was an MRI and I was given antibiotics for 3 weeks, and second follow-up CT scan . Both scans demonstrate complete opacification of right maxillary sinus with no change after antibiotics and saline wash; and both scans demonstrate prominent thickening or mucus in both right air cells and frontal sinus. There is also a mass in the left maxillary sinus, which appears to be bigger that first MRI scan done 4.5 weeks ago. Have never had any sinus problems, no hay fever , allergies , etc. Am 46 yr old woman, on and off smoker. What are the possible diagnosis please. Thanks

hi,i am 50 yrs old (smoker) and have been complaining of congestion since many years.The doc suggested a ncct says that i have a focal small polyp measuring 10*7 mm on anterior wall of left maxillary sinus. what does this mean? does it require surgery? how can it be treated?

I continuously get pains and feel lots of pressure around my right maxillary sinus. I get them about once every 2-3 months and only only the right side of my face. I used to think it was maxillary sinusitis, but I do not have yellow/green mucus nor do I have problems breathing. What else could possibly cause this re-occurring pain and minor swelling around the maxillary sinuses?

Was out in 9 degree weather this AM for about 20 minutes. When I came back into the house I noticed difficulty breathing - as if I could not get enough air in my lungs. I have a lung nodule in the lower right lobe with collapsing lung around the nodule - the nodule is still small.
