CA 2127705

Contrast agents comprising microbubble-generating carbohydrate microparticles having a surfactant admixed within the microparticulate structure (with the proviso that the surfactant is not a saturated C10-20 fatty acid when the microparticulate carbohydrate is galactose) exhibit useful levels of contrast efficiency and/or stability and may be used in diagnostic applications such as ultrasound and MR imaging.

Agents de contraste comportant des microparticules glucidiques aptes à générer des microbulles et dotées d'un tensio-actif mélangé à l'intérieur de la structure microparticulaire (à condition que le tensio-actif ne soit pas un acide gras C10-20 saturé lorsque le glucide microparticulaire est la galactose), présentant une efficacité de contraste et/ou une stabilité précieuse(s), et pouvant s'utiliser dans les applications diagnostiques telles que l'imagerie par ultrasons et par résonance magnétique.
