Book excerpt: The new edition of this popular textbook of pediatric radiology presents a clear and concise overview of pediatric disease in the neonate, infant, and young child. Organized by organ system, each chapter covers normal anatomy and variations, congenital anomalies, and common disease processes. Many normal films are included as a basis for understanding pathology and recognizing normal variants that are easily confused with abnormal findings. New to the Fifth Edition: an appendix of differential diagnosis/summary tables for quick reference, expanded chapters on the abdomen and head, and material on 3-D imaging and HRCT.
