Abstract
The present invention relates to contrast agents comprising microbubble-generating carbohydrate particles having a surfactant admixed within the microparticulate structure, wherein the microbubbles generated by the microparticles comprise a biocompatible low molecular weight fluorinated hydrocarbon.
