Gas-filled microspheres with fluorine-containing shells (GAS-FILLED MICROSPHERES WITH FLUORINE CONTAINING SHELLS)

摘要

The present invention relates to an improved ultrasound contrast agent comprising an aqueous suspension of microspheres consisting of at least one gas, preferably perfluorocarbons, encapsulated in an elastic shell of a biocompatible fluorine-containing amphipathic substance, a method for the preparation and improvement of microspheres And provides a diagnostic imaging method using the contrast agent.
