In vivo biodistribution of radioactivity at 1, 6, and 24 h after injection of ${}^{125}\mathrm{I}$-PSMA-Cys-Db (a) and ${}^{125}\mathrm{I}$-PSMA-Cys-Db-ICG (b) into mice bearing PC3-PSMA+ and PC3-PSMA− tumors, expressed as % injected dose/g of tissue. Data are represented as $\text{mean}\pm \mathrm{s}.\mathrm{e}.\mathrm{m}.$ $n=3$ to 4. * % injected dose for thyroid.
