This invention relates to an oil-in-water emulsion that is of a water-isoluble gas-forming chemical and a stabilizer, the emulsion being capable of forming microbubbles of gas upon application of ultrasonic energy. This composition allows for site-specific imaging as the image-enhancing bubbles can be released upon the application of ultrasonic energy at the specific location where the image is desired.

Cette invention se rapporte à une émulsion huile-dans-l'eau qui se compose d'un produit chimique contenant un gaz insoluble dans l'eau et d'un stabilisateur, cette émulsion étant capable de former des microbulles de gaz lors de l'application de l'énergie ultrasonique. Cette composition est bien adaptée à la formation d'images d'un site spécifique, étant donné que les bulles améliorant l'image peuvent être libérées lors de l'application de l'énergie ultrasonique à l'emplacement spécifique où l'image est désirée.
