Grids are typically used when:
1) Part measures more than 10 cm
2) At least 60 kVp needed for the exam
3) Part transmits little scatter radiation

Question

Quizplus · Accepted Answer

Grids are used to improve image quality by absorbing scatter radiation, which is more prevalent in thicker body parts (more than 10 cm) and when higher kVp settings (at least 60 kVp) are used. The statement about parts transmitting little scatter radiation is incorrect because grids are actually used when there is a significant amount of scatter radiation.
