The idea for this book grew out of our experience in teaching pediatric radiology to clinicians and students. Clearly, there is a strong desire on the part of those taking care of children to familiarize themselves with the rudiments of the pediatric radiograph. While radiologists have primary responsibility for the interpretation of films, clinicians bring valuable insight and information. Often they present additional important data or ask searching questions that prompt a re-evaluation of the films so that a more appropriate diagnosis may be obtained
