Echo‐Enhancing (Contrast) Agents

Echo‐Enhancing (Contrast) Agents Microbubbles enhance ultrasonic signals, because they resonate in the ultrasound beam to boost the intensity by approximately 20 dB. This can be used to rescue failed B-mode and Doppler studies. However, it can also extend both methods into previously impossible applications, including evaluating the microvasculature of the myocardium and of tumors. Because the transit of an injected bolus can be tracked, transit time curves can be generated; these transit time curves may provide features that can discriminate between benign and malignant vasculature. New types of microbubble agents targeted to specific tissue types are under development; they may prove useful as therapeutic and diagnostic agents. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Ultrasound quarterly Wolters Kluwer Health

Abstract

Microbubbles enhance ultrasonic signals, because they resonate in the ultrasound beam to boost the intensity by approximately 20 dB. This can be used to rescue failed B-mode and Doppler studies. However, it can also extend both methods into previously impossible applications, including evaluating the microvasculature of the myocardium and of tumors. Because the transit of an injected bolus can be tracked, transit time curves can be generated; these transit time curves may provide features that can discriminate between benign and malignant vasculature. New types of microbubble agents targeted to specific tissue types are under development; they may prove useful as therapeutic and diagnostic agents.
