Tagging of Breast Tumors for Excision and Specimen Radiography and of Sentinel Nodes for Ultrasound-Guided Localization Using Novel Particulate Agents
Abstract
During the first year, we identified a radiopaque tumor-marking agent and optimized the dose. During the second year we worked on coloring the agent and worked on the second agent for sentinel node detection to improve upon the water-soluble dye. Scope: We could not color the radiopaque perfluorocarbon (PFC) emulsion but successfully suspended India Ink within it. The optimum dose of the mixture was injected in tumors. We followed the black tract to locate and remove the tumor at 72 hours. The resected specimen was then radiographed. We began the work to accomplish the 3rd goal, the identification of the sentinel node.
