[99mTc]TRODAT-1: A novel technetium-99m complex as a dopamine transporter imaging agent

Abstract: Technetium-99m is the most commonly used radionuclide in routine nuclear medicine imaging procedures. Development of 99mTc-labeled receptor-specific imaging agents for studying the central nervous system is potentially useful for evaluation of brain function in normal and disease states. A novel 99mTc-labeled tropane derivative, [99mTc]TRODAT-1, which is useful as a potential CNS dopamine transporter imaging agent, was evaluated and characterized. After i. v. injection into rats, [99mTc]TRODAT-1 displayed spec… Show more

“…The technetium based 99m Tc-TRODAT-1 has the advantage of being relatively inexpensive and available in kit form. The easy preparation of 99m Tc-TRODAT-1 from lyophilized kits could be an ideal agent for daily clinical application [16]. However, its specific signal is lower than the 123 I-based SPECT tracers.…”

“…Radioligands for use with SPECT are mostly labeled with γ-emitting iodine-123 ( t 1/2 = 13.2 h). Only rarely has technetium-99m ( t 1/2 = 6.0 h) been applied with some success [9, 10]. Both iodine-123 and technetium-99m are available commercially.…”
