Filed: 1996-02-14
Abstract: PURPOSE: To obtain a contrasting agent for ultrasonic diagnosis for human and animal, having uniform quality and high preservability and achieving sufficient contrasting effect at a small administration dose. CONSTITUTION: An O/W-type emulsion composed of an aqueous medium and a disperse phase consisting of a water-immiscible liquid having a boiling point of 5-60 deg.C is irradiated with ultrasonic radiation. The disperse phase is composed of a fluorine-containing compound (e.g. dodecafluoropentane) and its amount is 0.00001-50wt.% based on the total emulsion. A continuous phase is prepared by using water as the aqueous medium and compounding 0.001-10wt.% of a surfactant [e.g. Zonyl(R) (DuPont)] and 0.001-75wt.% of a thickener (e.g. polyoxyethylene polypropylene) for improving the stability of the emulsion. The disperse phase is added to the continuous phase, the mixture is emulsified and the obtained O/W-type emulsion is irradiated with ultrasonic wave of 5,000-50,000Hz. The evaporation of the disperse phase is promoted by the cavitation effect caused by the ultrasonic treatment.
