    摘要： Emulsions preferably of nanoparticles formed from high boiling liquid perfluorochemical substances, said particles coated with a lipid/surfactant coating are made specific to regions of activated endothelial cells by coupling said nanoparticles to a ligand specific for αvβ3 integrin, other than an antibody. The nanoparticles may further include biologically active agents, radionuclides, or other imaging agents.

    摘要： Disclosed herein is a technique for performing medical imaging on a region of interest (ROI) wherein information theoretic signal receivers are used to enhance the detection and monitoring of pathologies such as angiogenesis and muscular dystrophy. Examples of information theoretic signal receivers that can be used in the practice of the invention include Shannon entropy signal receivers, continuous limit Shannon entropy signal receivers, Renyi entropy signal receivers, specific heat analog signal receivers, and thermodynamic energy analog signal receivers. The contrast enhancement provided by contrast agents, either targeted contrast agents or bubble-based contrast agents, is enhanced through the use of such information theoretic signal receivers. Further still, the contrast agents can be heated to further enhance visualization with information theoretic signal receivers.

    摘要： An improved contrast agent for magnetic resonance imaging comprises particles to each of which is coupled a multiplicity of chelating agents containing paramagnetic ions. In the improved agent, the position of the ion is offset from the surface of the particle so as to improve the relaxivity imparted by the contrast agent. A tether offsetting the chelate from the surface of the particle may optionally contain cleavage sites permitting more facile excretion of the chelated paramagnetic ion.

    摘要： A method for ligand-based binding of lipid encapsulated particles to molecular epitopes on a surface in vivo or in vitro comprises sequentially administering (a) a site specific ligand activated with a biotin activating agent; (b) an avidin activating agent; and (c) lipid encapsulated particles activated with a biotin activating agent, whereby the ligand is conjugated to the particles through an avidin-biotin interaction and the resulting conjugate is bound to the molecular epitopes on such surface. The conjugate is effective for imaging by x-ray, ultrasound, magnetic resonance or positron emission tomography. Compositions for use in ultrasonic imaging of natural or synthetic surfaces and for enhancing the acoustic reflectivity thereof are also disclosed.

    摘要： MRI contrast agents that employ paramagnetic agents and chemical exchange saturation transfer (paraCEST) and which are coupled to targeted particulate delivery vehicles provide sufficient concentration of the paraCEST contrast agents to obtain useful images of target tissues or organs. In addition, the image contrast may be switched on or off with a presaturation radio frequency pulse, avoiding the necessity obtaining pre-injection and post-injection images.
