Color-flow Doppler studies can depict?

• A. Motion, Direction, and Velocity of blood flow through
• B. Distance
• C. Temperature
• D. Acoustic impedance

Answer: (A)

Color-flow Doppler uses the Doppler effect to detect motion of red blood cells and then maps that information onto the ultrasound image with color. The resulting color overlay shows where blood is moving (motion), which direction the flow is traveling relative to the probe (toward or away), and an estimate of how fast that flow is (velocity). This combination is what makes color-flow Doppler so useful for assessing vessels and detecting abnormal flow patterns. It does not directly provide distance measurements, temperature, or acoustic impedance. Distance would come from measuring anatomy on the grayscale image, temperature is not something ultrasound measures, and impedance is a tissue property that governs reflections rather than giving a flow map.
