Question

Quizplus · Accepted Answer

Radiographic grids are recommended for chest radiography with exposure factors using 100 kV or greater to reduce scatter radiation and improve image contrast. Grids are not necessary for exposure factors below 80 kV, as scatter radiation is minimal at these low energies. Grids may also not be required for all pediatric patients, as their smaller body size may not produce significant scatter radiation.
