What is the primary disadvantage of using a high-ratio grid?

The primary disadvantage of using a high-ratio grid is that it results in increased patient dose. High-ratio grids are designed to absorb a greater amount of scattered radiation, which can enhance image contrast and quality. However, to achieve this, they require the x-ray beam to be more collimated, which can lead to higher exposure settings to ensure adequate penetration of the primary beam through the grid. Consequently, this increased exposure translates to a higher dose of radiation for the patient.

In contrast, while a high-ratio grid improves image quality by reducing scatter, it necessitates adjustments in technique that ultimately impact patient safety through increased radiation exposure. Factors like image blurriness, cost, and patient dose degradation are less relevant in this context, as these do not typically correlate directly with the use of high-ratio grids in the same way. Thus, the focus on dose is critical when evaluating the implications of utilizing high-ratio grids in radiographic practices.
