I wrote a research paper over a year ago for an undergraduate course I took in medical imaging. It is about imaging of the paranasal sinuses. Further topics include the diagnosis of sinusitis and chronic infection along with techniques in using 3-D CT to aid in image guided surgery. It is worth checking out if these topics interest you and/or you have problems with your sinuses. The document has been uploaded to docstoc and is below for your enjoyment.
Wife complains that I snore and I have frequent congestion. Is this likely sinusitis?
Could be, but could be other things as well. Why don’t you get evaluated by a physician such as an ear nose and throat doctor?
