USPTO Abstract

A microbubble-type ultrasonic imaging agent is pro­vided comprising a parenterally-administerable aqueous medium containing a dispersion of microspheres predominantly of di­ameters less than 10 microns, wherein the microspheres consist of gas microbubbles encapsulated with water-insolubilized bio­compatible material. The imaging agent is characterized by having a concentration of greater than 100 x 10⁶ microspheres per milliliter, and a stability such that this concentration is maintained for over 4 weeks at a temperature of 20 to 25°C. A preferred method of producing the imaging agent is also dis­closed.
