Remember that scattered radiation reaches the image receptor in a way that places a uniform layer of “grey ick” in excess of the anatomical facts we're seeking to visualize. As the level of scatter achieving the impression receptor boosts, the layer of grey ick cuts down the topic distinction dissimilarities between similar anatomical structures, decreasing distinction.
