Pediatric Immobilization and Dose
A 4-year-old child (weight 16 kg) is scheduled for a CT abdomen/pelvis with IV contrast for suspected appendicitis. The child is anxious and uncooperative. The department has a child life specialist available, but she is busy with another patient for 15 minutes. The CT scanner has pediatric protocols with automatic exposure control (AEC) and iterative reconstruction. The referring physician requests a low-dose protocol. The child's parent is present and asks if they can hold the child during the scan.
1. What are the appropriate strategies to manage the child's anxiety and obtain a diagnostic scan while minimizing radiation dose?

Strategies: Use child life specialist if available within a reasonable time; otherwise, employ distraction techniques (toys, video). Parental presence with proper shielding (lead apron) can help if the parent is not pregnant and understands risks. Use immobilization devices (papoose board) only if necessary and with parental consent. Use pediatric low-dose protocol with AEC and iterative reconstruction. Reduce scan range to area of interest. Consider oral or IV sedation only if non-invasive methods fail and with appropriate monitoring. The technologist should not allow the parent to hold the child during the scan without shielding and consent, but if the parent holds, they must wear lead apron and the child should be positioned properly.
2. How should the technologist address the parent's request to hold the child during the scan?
Read the worked answer
The technologist should explain that while parental presence can be comforting, holding the child during the scan exposes the parent to radiation. If the parent insists, provide a lead apron and ensure they are not pregnant. However, the preferred approach is to use immobilization or distraction. The technologist should also explain the low-dose protocol and that the benefit of the scan outweighs the small risk. Document the conversation.
