title: Section 6--mechanical bioeffects in the presence of gas-carrier ultrasound contrast agents. American Institute of Ultrasound in Medicine.
abstract: This review addresses the issue of mechanical ultrasound-induced bioeffects in the presence of gas carrier contrast agents (GCAs). Here, the term "contrast agent" refers to those agents that provide ultrasound contrast by being composed of microbubbles, encapsulated or not, containing one or more gases. Provided in this section are summaries on how contrast agents work, some of their current uses, and the potential for bioeffects associated with their presence in an ultrasonic field.
