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