What is true regarding grid use in fluoroscopy?

When it comes to the use of grids in fluoroscopy, it is key to understand the operational differences between fluoroscopic and standard radiographic imaging. The correct assertion highlights that grid ratios typically used in fluoroscopy are generally lower compared to those used in radiography.

In fluoroscopy, the primary aim is to view dynamic processes in real time, such as movement within the body or the flow of contrast agents. Because of this, patient motion and the need for quick adjustments to imaging techniques necessitate the use of lower grid ratios. Lower grid ratios allow for greater flexibility and reduce the risk of motion artifacts, ensuring clearer images without the added complexity associated with high-ratio grids.

Higher grid ratios, which are often employed in static radiographic procedures, may impede the efficient capture of dynamic images and can lead to increased patient dose from scatter radiation. Thus, the practical application of grids in fluoroscopy requires lower ratios to achieve the best balance between image clarity and patient safety, which is encapsulated in the correct answer.
