  • Patent number: 8642013
    Abstract: Compositions and methods are disclosed for evaluating a subject's vasculature integrity, for differentiating between a malignant lesion and a benign lesion, for evaluating the accessibility of a tumor to nano-sized therapeutics, for treating tumors, and for live or real time monitoring of a nano-probe's biodistribution.

  • Publication number: 20130190605
    Abstract: Methods and compositions are provided for objectively characterizing a pathological lesion in a patient. The method comprises: introducing into the patient a contrast enhancing agent; subjecting the patient to at least one of magnetic resonance imaging and computed tomography to obtain an image; and applying a 3-D autocorrelation function to a subdomain of interest of the image to obtain at least one 3-D autocorrelation spectrum. The method may further comprise comparing the at least one 3-D autocorrelation spectrum to a pre-existing 3-D autocorrelation spectrum that is characteristic for the pathological lesion. In one example, the methods and compositions may be useful for identifying and objectively characterizing amyloid plaque deposits characteristic of Alzheimer's Disease.

  • Publication number: 20120003159
    Abstract: Examples of compositions of liposomes and methods of making the same containing high concentrations of contrast-enhancing agents for computed tomography are provided. Example compositions of such liposomes, when administered to a subject, provide for increased contrast of extended duration, as measured by computed tomography, in the bloodstream and other tissues of the subject. Also provided are example methods for making the liposomes stable, that is, resistant to leakage of the contrast-enhancing agents, including the extrusion of the liposomes at high pressures and at high flow rates per total pore area of the extrusion filters.
