As the amount of contrast media increases in a patient, the contrast enhancement in the resulting images also increases. Contrast media are substances that enhance the visibility of internal structures in imaging, making them clearer against surrounding tissue. Therefore, with more contrast media injected or administered, there is typically a more pronounced distinction between the target structures and their environments, leading to improved image contrast.

This phenomenon results in greater contrast enhancement, allowing for better visualization of anatomical details or lesions. While this option reflects a correct understanding of how contrast media operates, it's essential to note that other factors might similarly change in complex ways depending on several conditions, such as imaging settings and patient response. However, increased contrast media directly correlates with enhanced visibility, making the selected response accurate.
