Abstract
Ultrasonic imaging agents comprising an aqueous suspension of negatively buoyant aspherical microdroplets composed of a biocompatible liquid core encapsulated by a shell of amphiphilic biocompatible material are prepared by milling a mixture of a solution of the shell material and vaporized liquid and cooling the milled mixture to below the boiling point of the liquid.
