Advances development of 64CuCl 2 in the diagnosis and treatment of tumor and disease of abnormal copper metabolism / 中华核医学与分子影像杂志

ABSTRACT

Copper is an essential metal element for human metabolism. Copper homeostasis can lead to inherited disorders of copper metabolism and also play an important role in tumor proliferation. In recent years, great progress has been made in the research and development of radioactive metal nuclide tracers, and molecular imaging quickly becomes a new inspection technology for detecting copper metabolism. 64CuCl 2 carries out PET imaging diagnosis of diseases with abnormal copper metabolism and tumors with high copper metabolism through real-time tracking of changes of copper ions in the body. At the same time, β - decay and electron capture of 64CuCl 2 have a therapeutic effect, and can be directly used for tumor nuclide therapy. Therefore, 64CuCl 2, as an integrated radiopharmaceutical for diagnosis and treatment, is the current research focus of molecular imaging. This article reviews 64CuCl 2 preparation, biological metabolism and its application in the diagnosis and treatment of abnormal copper metabolism diseases and tumors.
