Gamma camera images of rats injected with Tc-99m-EFAH: Rats injected with approximately 500 μCi of Tc-99m-EFAH were imaged in a NanoSPECT system. A dynamic image acquisition of Tc-99m-EFAH kinetics in the first 30 min of intravenous administration (upper panel) was followed by static images (at 0.5, 2, 4 and 24 h) showing accumulation of Tc-99m-EFAH in liver and gut.
