ABSTRACT:
An ultrasonic imaging technique is disclosed which uses microbubbles as echo contrast agents. In general the method employs maintenance of an ultrasound signal while the contrast agent is intravenously injected into a mammal. Once all the contrast agent has been injected and transmission of the signal is suspended for a period of time sufficient for the microbubbles perfuse the organ of interest. Transmission of the ultrasound signal is then resumed and peak contrast images are obtained which rival more complicated imaging procedures such as nuclear resonance imaging.
