Improvements in or relating to contrast agents

Abstract

Ultrasound contrast agents comprising microbubbles of gas or a gas precusor encapsulated in a protein shell, e.g. of human serum albumin, the protein being crosslinked with biodegradable crosslinking groups, exhibit stability in vivo upon administration so as to permit ultrasound visualisation while allowing rapid subsequent elimination from the system.
