  • Publication number: 20120003160
    Abstract: Methods for performing macrophage-enhanced MRI, utilizing a macrophage imaging agent, in a single imaging session are provided. The macrophage imaging agent may be an ultrasmall superparamagnetic iron oxide particle. One embodiment includes administering a macrophage imaging agent to the subject during an administration session then allowing a passage of time sufficient for accumulation of the agent in macrophages of the subject. Subsequently, in a single imaging session, a macrophage-enhanced magnetic resonance image is acquired to target macrophages and a different magnetic resonance image is acquired to target physiological phenomenon other than macrophages. Additional embodiments provide methods wherein the acquisition of a different magnetic resonance image is achieved by vascular-enhanced MRI protocols or perfusion-enhanced MRI protocols, or combinations thereof. Further embodiments provide methods for utilizing acquired images in assessment of treatment of disease.

  • Publication number: 20090004113
    Abstract: Methods for assessing stage of cancer in a subject are provided, comprising administering a macrophage imaging agent to the subject, making a magnetic resonance image of regions of the subject's body at cancer risk, and using the image to assess macrophage density and displacement associated with any primary cancer or metastatic cancer in the subject, such density and displacement being indicative of neoplasia. The macrophage imaging agent may be an ultrasmall superparamagnetic iron oxide particle and in particular embodiments, the macrophage imaging agent has a blood half-life sufficient to permit microphage trapping throughout the regions at cancer risk. Additional embodiments provide methods for assessing efficacy of an anticancer treatment in a subject, methods for determining frequency of follow-up MEMRI evaluation in a subject, methods for determining metastatic potential of cancer foci in a subject, and methods for determining prognosis of cancer in a subject.
