In ultrasound imaging, high contrast results in which of the following?

Explanation:
High contrast means the display uses a narrow range of echo amplitudes mapped to grayscale, so only very bright and very dark signals are shown. The system compresses the dynamic range, resulting in fewer gray shades. This makes borders and interfaces stand out more clearly, but it reduces subtle differences between tissues. Therefore, high contrast produces fewer shades of gray. Increasing shades of gray would come with a broader dynamic range (lower contrast), and speckle size is not directly changed by contrast settings.
