Appropriateness of radiology procedures performed in children with gastrointestinal symptoms and conditions.

Background & Aims: Exposure to ionizing radiation from diagnostic imaging procedures (DIPs) has been associated with an increased risk of cancer in children. In particular, gastrointestinal imaging has been identified as a significant factor that contributes to exposure of children to radiation during diagnostic procedures. We performed a longitudinal assessment of gastrointestinal-associated DIPs to identify practices that might be targeted to reduce exposure of pediatric patients to radiation.
