Method of preparing gas-filled polymer matrix microparticles useful for echographic imaging |
| abstract |
A method is provided to prepare gas-filled, porous microparticles having a polymer matrix interior which are useful as ultrasound echogenic contrast agents. An oil-in-water suspension is formed, both phases are frozen, then the aqueous and nonaqueous frozen phases are removed by sublimation. The resulting porous microparticles can receive a gas and be used as an ultrasound contrast agent. |
