What best practice minimizes radiation exposure in pediatric imaging?

What best practice minimizes radiation exposure in pediatric imaging?

• A. Apply ALARA principles; prefer ultrasound or MRI when appropriate; tailor CT dose.
• B. Use the highest CT dose possible for clarity.
• C. Avoid ultrasound altogether.
• D. Use MRI only for all imaging without exceptions.

Answer: (A)

Minimizing radiation exposure in pediatric imaging hinges on applying ALARA, because children are more radiosensitive and have a longer lifetime during which radiation effects could emerge. When possible, use ultrasound or MRI to answer the clinical question, since these modalities avoid ionizing radiation altogether. If CT or other ionizing imaging is necessary, tailor the examination to the child’s size and clinical need: lower the dose by adjusting kVp and mA to pediatric levels, limit the scanned area and the number of phases, and use dose-optimization technologies such as automatic exposure control and iterative reconstruction. This approach preserves diagnostic quality while reducing radiation dose, balancing the need for accurate imaging with the safety of the patient.
