Abstract
Image enhancing contrast agents for use in diagnostic and/or therapeutic methods, particularly in the form of gas-filled microvesicles, with enhanced stability. The gas-filled microvesicles are stabilized by a layer of amphiphilic material and comprise from 0.15% to 1.0% by moles of a lipid bearing a hydrophilic polymer. The lipid bearing a hydrophilic polymer is preferably a phospholipid linked to polyethyleneglycol.
