摘要：
Ferritin or iron-based image enhancement agents identify target tissue for treatment or ablation and are heated by microwave absorption. Microwave heat substrates enhance microwave hyperthermal ablation treatment, and may be percutaneously delivered and imaged by x-ray CT during placement of the microwave treatment antenna, allowing more precise positioning and more complete ablation of a tumor site. One method of treating a target tissue uses image-guided delivery of a heat substrate with a reverse-phase change polymer, and may apply energy to fix a mass of the material in the tissue. The fixed polymer may increase hyperthermia, form a thermal boundary, or blockade a vessel or passage so as to reduce or prevent undesired conductive cooling by contiguous tissue, or may deliver a localized treatment drug at the site, upon heating or as it degrades over time.
