In radiography, the use of radiographic grids is the best-known, most significant, and effective means of eliminating scatter radiation from an image. Scatter radiation can decrease the contrast of an image and prevent visualization of details, which compromises image quality. Because contrast and image detail are 2 of the most important elements used to create a superior image, using radiographic grids can positively impact the overall image quality. The goal of this article is to review concepts and grid applications, as well as provide an update on the requirements for grid utilization for digital radiologic technologists.
