| 摘要 |
Novel contrast media for use in ultrasonic imaging are described. Such contrast media may be comprised of an aqueous solution of one or more biocompatible polymers, wherein said biocompatible polymers are coated with and/or in admixture with at least one silicon containing compound. Alternatively, the contrast media may be comprised of an aqueous solution of one or more biocompatible synthetic polymers, or an aqueous solution of cellulose. The contrast media may be employed, if desired, with anti-gas agents and/or suspending agents.
