What is the primary purpose of using a grid during radiographic procedures?

Using a grid during radiographic procedures primarily serves to improve image contrast. Grids are designed to absorb scattered radiation that occurs when X-rays pass through the body and interact with tissues. Scattered radiation can reduce the clarity and contrast of the image, leading to a less diagnostic quality.

By filtering out this unwanted scattered radiation before it reaches the imaging receptor, grids enhance the visibility of the structures of interest. This results in images that are sharper and provide greater differentiation between tissues of varying densities. High contrast is essential for accurately diagnosing conditions and assessing anatomy.

While using a grid can influence factors such as patient dose and the required exposure settings (mAs), these are secondary considerations compared to the primary function of enhancing image quality through improved contrast.
