“What does an x-ray of the sinuses show?”

X-ray of the paranasal sinuses does show descent 2D images of a 3dimentional object so we must acquire more than one(orthogonal)view most of the time(an exception would be in children in an effort to reduce radiation. A CT scan of the sinuses is a much more detailed(better resolution/detailexam as it provides much more resolution of sinus anatomy and a better chance of finding more subtle abnormalities when present and possibly a cause for the patients signs and symptoms. Unfortunately a CT scan is much more expensive than plain x-rays. Thanks, Dr FMB, MD
