摘要:
Agents de constraste comportant des microparticules glucidiques hydrosolubles aptes à générer des microbulles et mélangées à un produit non tensio-actif constituant au moins 10 % en poids de la composition totale et moins hydrosoluble que le glucide. Lesdits agents de constraste présentent une efficacité de contraste et/ou une stabilité précieuse(s), et peuvent s'utiliser dans les applications diagnostiques telles que l'imagerie par ultrasons et par résonance magnétique.
