What best describes the role of immobilization in pediatric imaging?

• A. It reduces the need for repeat exposures by minimizing movement.
• B. It increases the radiation dose.
• C. It has no impact on exposure.
• D. It replaces shielding.

Answer: (A)

Keeping pediatric patients still during imaging is essential because motion creates blur that can obscure anatomy and degrade diagnostic quality, often requiring a repeat study. Immobilization helps by using gentle restraints, supports, and positioning aids, along with calm, child-friendly communication, so the child stays still throughout the exposure. When movement is minimized, the first image is more likely to be acceptable, reducing the need for repeats. Since repeats expose the patient to additional radiation, immobilization directly helps lower the total dose and improves image quality. It does not increase radiation dose, nor does it replace shielding, which is used to protect radiosensitive tissues.
