Ultrasound contrast media

Ultrasound contrast media is used to increase the contrast of the sonogram image by enhancing the reflection of the ultrasound waves. This occurs due to the difference in the ability of the contrast media and the soft tissue to reflect the ultrasound wave.

The ultrasound contrast media can be gas-filled microbubbles that are used to image blood flow or perfusion, or can be site-targeted microbubbles that can attach to specific markers.
