Advantages of table-top radiography in pediatric IVPs

Evidence is presented to support the use of a nongrid table-top procedure for pediatric IVPs. The patient dose and image quality is compared in grid and nongrid techniques using identical film-screen systems. All projections are KUBs of children with abdominal thicknesses less than 13 cm who are involved in IVP examinations. Image quality is shown to be affected adversely beyond 13 cm. The use of the table-top method is helpful to the radiologist and technologist and beneficial to the patient.
