Optison is an ultrasound contrast agent that is used to improve the quality of an echocardiogram (ultrasound of the heart). This medicine works by changing the way ultrasound waves travel within your heart. This helps the ultrasound portray a sharper image of your heart.

Optison is used to allow certain segments of the heart to be seen more clearly on an echocardiogram.
