CXR practice cases
Normal PA CXR and normal axial CT image in the lower lungs
It is important to be systematic in your approach to each different type of imaging study. There are several systems for looking at a CXR. It is a good idea to start by looking for any foreign objects, and then to use a short list to be sure you cover all areas, including bones, soft tissues, heart and lungs. For a CT, a different search pattern should be used, which will vary depending on the window that is being viewed. On a lung window image, like the one shown here, check for normal branching vascular structures and few if any markings in the outermost lung, and smooth pleural surfaces. It is always important on a CT or MR to check for symmetry between the two sides, in this case the lungs should be similar in attenuation.
