A quadruple isotope SPECT/CT imaging acquisition was performed on a rat. 450uCi (17MBq) of Tc99m-MDP, 1.4mCi (52MBq) of I123, 600uCi (22MBq) of In111, and 1mCi (37MBq) of Tl201-Chloride were administered to the rat. A 40-minute image acquisition was performed at 3 hours post-injection of the Tc99m/I123 and 1 hour post-injection of the In111/Tl201. From left to right, the image displays reconstructions of Tc99m (gray; bone uptake), I123 (purple; thyroid and small intestine uptake), In111 (blue; heart, liver, and intestine uptake), and Tl201 (red; kidney, liver, and heart uptake).
