Scatter radiation is not the result of photoelectric interactions but rather of Compton interactions. It decreases the visibility of anatomic structures by adding a layer of "noise" or unwanted exposure on the radiographic image, which does not contribute to the diagnostic information but rather obscures it, leading to lower image quality and contrast.
