Synthesis and characterization of a novel 99mTc analogue of *I-mIBG showing affinity for nor-epinephrine transport positive tumors

¹²³I/¹³¹I labeled meta-iodobenzylguanidine (mIBG) is a radiopharmaceutical used for diagnosis of neuroendocrine tumors (NET) related to neural crest origin. Present work evaluates a newly synthesized ^99mTc analogue of this radioiodinated derivative.
