Which adjustment is preferred when radiographic grids are used to reduce scatter?

Explanation:
When a grid is used, it improves image quality by absorbing scattered photons, but it also reduces the number of primary photons reaching the image receptor. To keep the same image density after this attenuation, you increase the number of photons produced, which is best done by raising the mAs. This boosts the overall exposure reaching the detector while keeping contrast more favorable than raising kVp, which would increase beam penetration and scatter and can degrade contrast even with a grid. Lowering mAs or lowering kVp would reduce receptor exposure and lead to an underexposed image.
