Pediatric radiology is the application of diagnostic radiology to aid in the understanding, diagnosis, therapy, and follow-up of diseases of infants and children. Pediatric radiologists have pursued additional, specialized training in performing and interpreting imaging of children of all ages, utilizing plain film radiology, ultrasound, CT, MRI, fluoroscopy and nuclear medicine. While pediatric radiologists are involved in many of the studies performed on children, other sub-specialists within the Department of Medical Imaging, assist in the care of pediatric patients.
