Final answer:
The Doppler color can be used on top of the Doppler-shifted ultrasound mode to better show blood flow. Doppler-shifted ultrasound uses color to indicate blood flow velocity, with the highest velocities shown in red and the lowest in blue.
Step-by-step explanation:
The Doppler color can be used on top of the Doppler-shifted ultrasound mode to better show blood flow.
Doppler-shifted ultrasound uses color to indicate blood flow velocity, with the highest velocities shown in red and the lowest in blue. This mode is particularly useful in visualizing blood flow in partially occluded arteries where the blood must move faster through the constriction to carry the same flow.
