This is done using microbubbles from agitated saline (a vial of saline shaken up). The bubbles reflect the ultrasound beam. This is from my personal knowledge as a physician and a patient who had a bubble study.

Ultrasound contrast consists of gas-filled bubbles that are given intravenously (that is, into your blood vessels).
Ultrasound devices send sound waves into your body and then interpret the echoes as images.
Normally, bodily fluids are difficult to distinguish from the surrounding tissue using ultrasound. Contrast (the bubbles) helps differentiate the two, increasing your overall resolution (ability to tell what is what when you look at the screen).
