Differentiated thyroid cancer(DTC)accounts for more than 95％of all thyroid cancers.99Tcm-3PRGD2 can specifically bind to integrin αvβ3 receptors highly expressed on the surfaces of neovascular endothelial cells and tumor cells in malignant tumors.With high specificity and safety,99Tcm-3PRGD2 can not only be used for diagnosing DTC and its metastases,but also evaluating the efficacy of anti-angiogenic and anti-αvβ3 therapies.99Tcm-MIBI is a non-specific tumor-avid imaging agent,which may improve diagnostic accuracy combined with 99Tcm-3PRGD2.The research progresses of 99Tcm-3PRGD2 and 99Tcm-MIBI for diagnosis and treatment of DTC were reviewed in this article.
