Synthesis and Characterization of Bismuth Beads for Trans Arterial Chemo Embolization Under Computed Tomography (CT) Guidance
Existing microsphere technologies are used as therapy for certain cancers. The therapy is by way of occlusion, when the microspheres are delivered into blood vessels that feed a tumor. The physical dimensions of the microspheres occlude the blood supply and thus, killing the tumor. Some microspheres have also been modified to bind protein, elute drugs, and reduce inflammatory reactions as part of the therapy. However, one technical short-coming of existing microsphere technology is a limited capability to be visualized in real-time.
