    摘要: A radiolabeled nucleoside analogue is provided, which includes radioactive iodine 123I/131I, and a nucleoside analogue selected from a group consisting of cytidine, thymidine, uridine, and a derivative thereof. A method for preparing the radiolabeled nucleoside analogue, and a use thereof are further provided. The nucleoside analogue, prepared through the preparation method with a short synthesis time and a high radiochemical yield, has a long in vivo physiological half life and a high stability in serum, and, as a radiopharmaceutical composition, is useful in development of tumor proliferation diagnosis or therapy prognosis evaluation, and further assists in observation of long-time in vivo metabolism of a drug.
