Computed tomography and ultrasound in the diagnosis and management of neuroblastoma

Gray-scale ultrasound and computed tomography were found to be diagnostically and clinically valuable in the study of 13 of 17 children with neuroblastoma. Use of ultrasound and computed tomography: (a) resulted in diagnoses not possible with conventional techniques, such as plain radiographs and excretory urograms; (b) defined more clearly the normal and pathologic anatomy in a three-dimensional perspective; (c) was an aid in evaluating extra-abdominal manifestations; and (d) permitted follow-up after surgery, radiation, and chemotherapy.
