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. www.mainlineent.com.

Imaging of sinuses: There are many sinuses of the cranium (skull) and facial bones. Disease of the sinuses or obstruction may be difficult to diagnosis. Tumors may occur from bone or sinus lining (mucocoeles) and obstruction may lead to fluid accumulation, pus and/or sinusitis. A computed axial tomography ("cat") scan will help to visualize and diagnosis sinus disease.
