    摘要: The invention relates to ultrasound contrast agents comprising vesicles comprising a protein capable of formation of gas-containing vesicles, wherein the vesicles contain gas which comprises sulphur hexafluoride or a low molecular weight fluorinated hydrocarbon. These contrast agents exhibit stability in vivo upon administration so as to permit ultrasound visualization while allowing rapid subsequent elimination from the system.

    摘要: This invention relates to ultrasound contrast agents in the form of microparticles comprising a biotolerable matrix (e.g. of a carbohydrate or an X-ray contrast agent) in association with a gas or a precursor therefor. The contrast agents are stabilized to enhance their in vivo stability and/or echogenicity by covalently modifying the structure of the matrix, e.g. to introduce crosslinking groups or to attach lipophilic groups and/or molecules. The covalent moieties may include biodegradable linkages to assist rapid subsequent elimination of the contrast agents from the system.

    摘要: Water insoluble iodinated esters of formula (I), in which R.sup.1 is a substituted or unsubstituted C.sub.1-20 aliphatic, C.sub.7-20 araliphatic or C.sub.6-20 aryl group or a C.sub.1-20 heterocyclic group having one or more hetero atoms selected from O, S and N; R.sup.2 is hydrogen or a substituted or unsubstituted C.sub.1-6 aliphatic, C.sub.6-10 aryl or C.sub.7-20 araliphatic group; and R.sup.3 is a group as defined above for R.sup.1, which may be the same as or different from R.sup.1, or R.sup.2 and R.sup.3 together represent a substituted or unsubstituted C.sub.1-4 alkylene group, the molecule containing at least one iodine atom and being metabolisable to products which are soluble in body fluids and are physiologically acceptable. The esters are useful in X-ray and ultrasound imaging, especially liver and spleen imaging.
