Methods and devices for enhanced ultrasound detection based upon changing temperature and ultrasound reflectivity of a temperature-dependent contrast agent bound to an ultrasound target are disclosed. The methods and devices can be used for enhanced imaging alone or in conjunction with drug delivery, with therapeutic approaches such as hyperthermia or cryotherapy or with other imaging modalities.

Emulsions preferably of nanoparticles formed from oil compounds coupled to a high Z number atom, said particles coated with a lipid/surfactant coating. The nanoparticles are made specific to targeted cells or tissues by coupling said nanoparticles to a ligand specific for the target cells or tissues. The nanoparticles may further include biologically active agents, radionuclides and/or other imaging agents.
最好是由与高 Z 数原子偶联的油化合物形成的纳米颗粒的乳液,所述颗粒涂有脂质/表面活性剂涂层。通过将纳米颗粒与目标细胞或组织的特异性配体偶联,使纳米颗粒对目标细胞或组织具有特异性。纳米粒子可进一步包括生物活性剂、放射性核素和/或其他成像剂。

The invention is directed to methods for the delivery of a therapeutic agent using lipid-encapsulated particles containing the therapeutic agent and ultrasound energy. For example, it particularly relates to the use of ultrasound with a lipid-encapsulated emulsion comprising an oil where the emulsion is coupled a targeting ligand and comprises a therapeutic agent.
