Production and Application of 123I-Labeled M-Iodobenzylguanidine (123I-MIBG)
131I-Labeled m-iodobenzylguanidine (131I-mIBG) was first synthesized by Wieland and co-workers1 and soon became widely used for diagnosis of neural crest tumors, such as pheochromocytoma2 and neuroblastoma.3 Because of I-123’s superior physical properties for scintigraphic imaging compared to I-131,4 123I-mIBG has become the preferred agent for diagnosis, staging, and clinical follow-up of patients with these tumors. In addition, 123I-mIBG has shown potential for cardiac applications, such as determination of regional myocardial adrenergic activity following myocardial infarctions5 and prioritization of candidates for heart transplantation.6
