Abstract
Ultrasonic imaging agents comprising an insoluble gas may be made by a new process of gas exchange. A solution is supersaturated with the insoluble gas and then contacted with a conventional air-filled microsphere suspension in order to effectuate a gas exchange process. The insoluble gas-containing microsphere exhibits increased pressure resistance and stability over microspheres in which the gas exchange was performed passively.
