Pediatric radiology is a subspecialty of radiology involving the imaging of fetuses, infants, children, adolescents, and young adults. Many paediatric radiologists practice at children's hospitals. Although some diseases seen in paediatrics are the same as that in adults, there are many conditions which are seen only in infants. The specialty has to take in account the dynamics of a growing body, from pre-term infants to large adolescents, where the organs follow growth patterns and phases. These require specialised imaging and treatment which is carried out in a Children's hospital, which has all the facilities necessary to treat children and their specific pathologies.
