    摘要: A gas emulsion forming composition comprising a dry, hollow, particulate, approximately microspherical material permeated with a gas or gas mixture, which upon dissolution in aqueous liquid forms a gas emulsion comprising a plurality of bubbles surrounded by a layer of at least a first and a second surfactant, wherein the first surfactant consists essentially of a phospholipid or mixture of phospholipids having at least one acyl chain which comprises at least 10 carbon atoms, and comprising at least about 5% w/w of total surfactant, and wherein the second surfactant may or may not be a phospholipid and is more water soluble than the first surfactant; kits for preparing such microbubbles; and methods for using such microbubbles as contrast agents.
