This fully updated second edition is a definitive guide to imaging and differential diagnosis for pediatric pulmonary diseases and disorders. This edition is fully updated to include coverage of the latest imaging and diagnostic techniques, modalities, and best practices. Beginning with clinical algorithms, chapters provide a framework for clinical diagnosis. This image-based text presents a comprehensive, multi-modality approach, with an emphasis on plain film and cross-sectional imaging.  The imaging sections, including a new chapter on pediatric thoracic MRI, are correlated with pathology and clinical findings to help readers learn what the modality of choice can enable them to see. This information and guidance is applied directly to diseases and disorders seen in everyday practice, including pleural effusion, focal lung disorders, pulmonary hypertension, cystic fibrosis, and asthma, as well as a new chapter on pediatric pulmonary embolism. In addition, a new chapter on the genetics of pediatric lung disorders has been added. This essential guide gives pediatric pulmonologists and radiologists the information to identify the differentials by symptom complex, accordingly determine what test would be effective, how to proceed, and to essentially provide the best care for their patients.
