Abstract
The present invention relates to contrast agents comprising microbubble-generating carbohydrate particles having a surfactant admixed within the microparticulate structure, with the proviso that the surfactant is not a saturated C.sub.10-20 fatty acid. The contrast agents exhibit useful levels of contrast efficiency and/or stability and may be used in diagnostic applications such as ultrasound and MR imaging.
