The purpose of this book is to provide the radiologist with information which is "as practical as possible" for the everyday use of computerized tomography (CT) in the field of cervical, thoracic, and musculoskeletal pathology. The approach is simple. For each region the following information is pre­ sented: (1) a general schematic introduction, summarizing the main indications for CT and its specific usefulness; (2) a series of pictures of normal structures with a precise and practical identification; and (3) a selection of pictures of pathological structures, with a description and a short comment, aimed at covering the largest possible field of CT indications and interests. This approach has been applied to the following areas: cervical pathology, with one section dealing with the larynx and hypopharynx; the thorax, specifi­ cally to pulmonary diseases, pleural and parietal pathology, and the mediasti­ num, with special sections dealing with tumours, the heart, and large vessels; the spine, which is of growing importance in clinical CT; and finally the pathol­ ogy of the musculoskeletal system in general, with special attention being paid to the developing field of orthopaedic CT measuring methods.
