What is one effect of using a grid during fluoroscopy?

• A. Increased patient movement
• B. Improved image clarity
• C. Higher patient exposure
• D. Reduced equipment cost

Answer: (B)

Using a grid during fluoroscopy plays a significant role in improving image clarity. Grids are designed to absorb scattered radiation that occurs when the X-ray beams pass through the body. This scattered radiation can create a haze or fog in the images, reducing the overall quality and detail. By placing a grid in the path of the X-rays, the amount of scatter reaching the image receptor is minimized, which enhances the contrast and sharpness of the resulting image. This is particularly important in fluoroscopy, where clear and detailed images are necessary for accurate diagnosis and assessment. The other options, such as increased patient movement, higher patient exposure, and reduced equipment cost, do not directly relate to the primary function of a grid in enhancing image quality. In fact, while the use of grids can lead to increased patient exposure due to the need for higher doses of radiation to maintain image quality, their main effect is the improvement of image clarity.
