Quizplus · Accepted Answer

Radiographic grids are typically required for chest radiography when exposure factors using 100 kV or greater are used. This is because higher kV settings result in more scattered radiation reaching the image receptor, leading to decreased image contrast. Using a grid helps remove some of this scattered radiation and improve overall image quality. Grids are not typically required for exposure factors using 80 kV or below, as the amount of scattered radiation produced is relatively low at these lower settings. There is no universal rule stating that grids are required for all adult or pediatric patients, although certain patients (such as those with thicker body habitus or those undergoing certain types of exams) may benefit from the use of a grid. Ultimately, the decision to use a grid should be based on the specific imaging scenario and the judgement of the technologist or radiologist involved.
