How do ascites affect the subject contrast of the abdomen?

Explanation:
Subject contrast in radiography comes from differences in how tissues attenuate X-rays. When ascites is present, a large amount of fluid fills the peritoneal cavity, creating a broad, uniform medium with attenuation close to water. This smooths out the density differences between neighboring structures—such as liver, bowel, and surrounding soft tissue—so their borders become less distinct. The result is a reduction in the overall contrast observed in the abdomen.
