Development of Tc-99m labeled tropanes: TRODAT-1, as a dopamine transporter imaging agent

Nucl Med Biol. 2001 Jul;28(5):505-8. doi: 10.1016/s0969-8051(01)00220-7.

Abstract

Advances in the technetium chemistry have significantly enhanced the development of Tc-99m radiopharmaceuticals for clinical use. Efforts in designing novel Tc-99m labeled receptor or site-specific imaging agents using [Tc(v)O](+3)N(2)S(2) core have produced useful imaging agents for single photo emission computed tomography (SPECT). The success in developing Tc-99m TRODAT-1 for CNS dopamine transporters (DAT) serves as the first example of Tc-99m site-specific imaging of human brain. New innovative Tc-99m labeled site-specific agents are particularly suitable to develop simple and useful routine diagnostic procedures.
