What is the trade-off of using a radiographic grid?

Explanation:
Using a radiographic grid improves image contrast by reducing scattered radiation reaching the image receptor. But because the grid also attenuates some of the primary beam, a higher exposure is needed to produce the same receptor exposure and brightness. That increase in exposure translates to a higher patient dose. The amount of dose increase depends on the grid’s characteristics (ratio and frequency): higher ratios generally require more exposure to maintain image quality. So the trade-off is better image contrast at the cost of increased patient radiation.
