  • Emulsions as contrast agents and method of use
    Patent number: 6030603
    Abstract: This invention relates to an oil-in-water emulsion that is of a water-insoluble gas-forming chemical and a stabilizer. The emulsion being capable of forming microbubbles of gas upon application of ultrasonic energy. This composition allows for site specific imaging as the image enhancing microbubbles can be released upon the application of ultrasonic energy at the specific location where the image is desired.
    Type: Grant
    Filed: December 23, 1997
    Date of Patent: February 29, 2000
    Assignee: Molecular Biosystems, Inc.
    Inventors: Rolf Lohrmann, Kenneth J. Widder, Ashwin M. Krishnan, Dung Kevin Hong, Jialun Meng
