Technetium agents

Technetium agents based on the technetium-99m (Tc-99m) radioisotope are frequently used agents in medical imaging. A radiopharmaceutical labeled with Tc-99m constitutes a co-ordination complex in which ligands bond to a central atom of Tc-99m by co-ordinate covalent bonds 4 .

The radioactive technetium radiotracer can be chelated to a number of different compounds to create specific radiopharmaceuticals and optimize the functional imaging of various structures:
