In pediatric radiography, besides technique and shielding, what practice improves dose efficiency?

• A. Repeat radiographs to ensure clarity.
• B. Use pediatric-specific exposure settings and limit scan range when possible.
• C. Always use max kVp.
• D. Avoid shielding.

Answer: (B)

Tailoring exposure to the child's size and limiting the area being imaged directly reduces the dose while preserving diagnostic quality. Using pediatric-specific exposure settings means selecting kVp and mAs appropriate for the child’s size, so you don’t waste dose with adult techniques or compromise image quality by underexposure. Limiting the scan range confines radiation to the region of interest, minimizing dose to surrounding tissues and avoiding unnecessary exposure. Repeating radiographs increases overall dose, maxing kVp without considering image quality can compromise diagnostic utility, and shielding, while important, is not the focus here. The combination of size-appropriate settings and restricted field of view provides the best improvement in dose efficiency.
