No radiotracers are currently available for imaging brain NIS activity. Here, we synthesized 6[124I]iodo-9-pentylpurine that can noninvasively measure iodide efflux from the brain and showed that the efflux rate of [124I]I− in NIS knockout mice was 84% lower than that of wild-type mice. Thus, 6-[124I]iodo-9-pentylpurine would be useful for imaging brain NIS activity.}, pages = {1717--1723}, title = {6-[124I]Iodo-9-pentylpurine for Imaging the Activity of the Sodium Iodide Symporter in the Brain}, volume = {63}, year = {2020} }
