The ability to differentiate between two regions having similar echogenicity is termed?

• A. Lateral resolution
• B. Contrast resolution
• C. Axial resolution
• D. Temporal resolution

Answer: (B)

Contrast resolution is the ability to differentiate two adjacent regions that have similar echogenicity. When two areas look nearly the same brightness on an ultrasound image, good contrast resolution lets you see a boundary between them and recognize subtle differences in tissue composition. This is different from axial or lateral resolution, which describe how closely you can separate two reflectors that are along the beam direction or across the beam width, respectively. Temporal resolution relates to how quickly frames are acquired and displayed, affecting motion depiction rather than static brightness differences.
