What impact does scattered radiation have on a radiographic image?

Scattered radiation significantly impacts the quality of a radiographic image by producing fog. When X-rays interact with matter, they may change direction and some will scatter away from the original path. This scattered radiation can reach the image receptor and contribute to a general haziness or fog on the radiographic image. This fog can obscure fine details and reduce the overall contrast between different tissues, making it harder to distinguish between them.

In contrast, the other choices do not accurately reflect the effects of scattered radiation. Scattered radiation does not increase contrast; instead, it tends to lower it, making images appear less sharp. Additionally, while grid cutoff refers to the loss of image density due to improper alignment of a grid with the X-ray beam, it does not relate to scattered radiation in a direct way. Finally, scattered radiation does not enhance detail; instead, it diminishes the ability to see fine details clearly, which is essential for accurate diagnosis.
