Abstract
Contrast echocardiography describes a variety of applications whereby ultrasound-enhancing agents composed of encapsulated microbubbles are used to image the blood pool during cardiovascular ultrasound. The overall justification for contrast echocardiography imaging is to improve accuracy of conventional echocardiography or to create new diagnostic capabilities. This chapter reviews some of the established clinical applications for contrast echocardiography with ultrasound-enhancing agents, including (1) left ventricular opacification (LVO) in resting studies to better assess regional or segmental function, (2) LVO for better quantification of ejection fraction and volumes, (3) LVO during stress echo, (4) myocardial perfusion imaging at rest and stress to assess for ischemic heart disease and viability, and (5) perfusion imaging of masses.
