The Ct chest anatomy is very important. There are so many things that can go wrong in one's chest and can only be detected on Ct. Xray can normally determine if one has pneumonia but ct can recognize the location and extent of pneumonia better. Pneumonia doesnt normally affect the whole chest. Ct can determine what lobes it is affecting and how bad the pneumonia is. Here is a picture of a chest ct without contrast. The chest is scanned without contrast to show fluids and pneumonia in the chest. Information found at www.radiologyinfo.com
