Which unit is used to express volume measurements in ultrasound contexts?

• A. Liter
• B. Cubic meters
• C. Cubic centimeters
• D. Square meters

Answer: (C)

In ultrasound contexts, volume is expressed in cubic centimeters because imaging often deals with small, centimeter-scale structures, so combining length, width, and height in centimeters yields a convenient volume in cm^3. One cubic centimeter equals one milliliter, which aligns with common clinical fluid and tissue measurements. Larger units like liters or cubic meters are impractical for typical anatomical volumes, and square meters measure area, not volume. So cubic centimeters is the most appropriate unit for volume in ultrasound scenarios.
