When image contrast is noted to be decreased due to high scatter production in adult fluoroscopic procedures, what action would improve image contrast?

Choosing to add a grid is a strategic approach to improving image contrast in fluoroscopic procedures when high scatter is present. Grids are designed to absorb scatter radiation while allowing the primary beam that contributes to the image to pass through. This selective absorption enhances the contrast of the image by reducing the fog that scatter radiation can cause, leading to clearer differentiation of structures within the image.

In fluoroscopy, scatter production often increases with larger patient thickness or higher radiation exposure, which can compromise the visual quality of the images. By incorporating a grid, the effective contrast of the fluoroscopic image can be significantly improved, enabling better visualization of anatomical details and pathological conditions.

Other options may not directly address the issue of scatter in the same way. For example, reducing exposure time may minimize motion blur but doesn't necessarily affect scatter levels. Increasing patient thickness would likely contribute to more scattering, worsening the contrast. Adjusting kVp settings could affect the overall penetration and exposure of the image but would not specifically target scatter reduction as effectively as employing a grid.
