  • Patent number: 11077214
    Abstract: The present application relates to compositions comprising an iodinated contrast agent and indocyanine green co-encapsulated inside a liposomal carrier, various uses thereof as well as methods for their preparation.
    Type: Grant
    Filed: May 26, 2014
    Date of Patent: August 3, 2021
    Assignee: University Health Network
    Inventors: Jinzi Zheng, David A. Jaffray, Christine Allen
  • Patent number: 9393326
    Abstract: There is provided signal modifying compositions for medical imaging comprising a carrier and signal modifying agents specific for two or more imaging modalities. The compositions are characterized by retention efficiency, with respect of the signal modifying agents that enables prolonged contrast imaging without significant depletion of the signal modifying agent from the carrier. The carriers of the present invention are lipid based or polymer based the physico-chemical properties of which can be modified to entrap or chelate different signal modifying agents and mixtures thereof and to target specific organs or tumors or tissues within a mammal.

  • Publication number: 20130261371
    Abstract: Imageable disruptable capsules containing a sensitizing agent or a protecting agent are used to enhance radiation therapy. Said capsules may be imaged by a non-invasive imaging modality, allowing for the determination of the precise timing to disrupt the capsule and release the sensitizing agent or protecting agent using an external energy source. This controlled and timed release of the sensitizing agent or protecting agent provides for enhanced radiation therapy by optimizing the delivery of the sensitizing agent or protecting agent to the target tissues. Systems comprising non-invasive imaging modalities, external energy sources and radiation energy sources are also taught for use with these imageable disruptable capsules.
