What does blue and red on a ultrasound mean?

A doctor has provided 1 answer

Vascular flow direct: Assigning color red and blue distinguishes the direction of vascular flow in relation to transducer. The assigned colors are random, but is best to standardize: flow from left side of image to right side of image is assigned red; opposite flow assigned blue.
