Abstract
Blood-pool ultrasound contrast agents (UCSs) have the ability to image blood flow in soft tissues, which can be visualized at capillary level. Color Doppler has been integrated in EUS equipment since the introduction of electronic transducers and is able to visualize blood flow and its direction in small arteries and veins but not blood flow in capillaries or perfusion. Visualization of perfusion by contrast agents represents a new step in flow imaging and may separate hyper- and hypoperfused areas in tissue. This may be useful for tissue characterization and identification of tumors or abscesses or to guide intervention and tissue sampling.
