    摘要: The invention relates to diagnostic ultrasound contrast agents comprising vesicles comprising an amphiphilic phospholipid material capable of formation of gas-containing vesicles wherein the vesicles contain gas which comprises sulphur hexafluoride. The contrast agents and vesicles exhibit good stability in vivo upon administration and may if desired incorporate biodegradable linkages so as to possess particularly desired levels of biodegradability.
