Exametazime is a diagnostic radiopharmaceutical agent commonly used for the preparation of Tc99m Exametazime injection. It acts as a chelating agent for the radioisotope technetium-99m to form a cationic complex. It is used in the detection of altered regional cerebral perfusion and for the radiolabeling of autologous leukocytes.
