Some aspects of the radiopharmaceutics of 99m-Tc-phytate.

This paper outlines the method of preparation of 99m-Tc-phytate and its use for scanning the reticuloendothelial system. The tissue distribution studies in mice and rats indicate that 99m-Tc-phytate is a safe and effective liver imaging agent. This was confirmed by preliminary studies in human subjects. The stability of the aqueous tin-phytate complex is remarkably good, and it could be successfully used for more than two months to prepare the labelled product.
