Why do I need to get at CT (cat) scan for my sinusitis?
Sinusitis is typically a diagnosis that usually can be made based on how you feel.  When your symptoms have not responded to medical therapy a CT scan may be ordered.  The CT is the best test for sinus inflammation, and is much better than an MRI.  It gives detailed information about the degree of swelling of the sinus lining and shows your nasal and sinus anatomy in detail.  Additionally, if the inside of your nose looks healthy (often with a camera called an endoscope) it is reasonable to get a CT scan to ensure that your symptoms are being caused by a sinus process and not by something else.  Lastly, a CT scan may be obtained for planning for surgery.
