This book begins with four introductory chapters devoted to airway physiology, anatomy, and anatomical and functional CT imaging methods. These chapters are followed by four chapters devoted to large airways disorders in adults, including airway stenoses, neoplasms, malacia and bronchiectasis. The next section is comprised of 5 chapters devoted to small airways disorders in adults, including asthma, infectious and non-infectious small airways disorders, obliterative bronchiolitis, and smoking-related airway diseases. The final two chapters are devoted to pediatric large and small airway disorders. This textbook is a collaborative project that has greatly benefited from the contributions of many expert authors from around the globe. The intended audience for this book is primarily radiologists and pulmonologists, but the content will likely also be of interest to thoracic surgeons, pulmonary pathologists, and other physicians who are involved in the care of patients with airway diseases.
