【摘要】 介绍一种快速、简便的碘（￣（１３１）Ｉ）标记ＭＩＢＧ（间位碘代苄胍）的新体系，抗坏血酸为还原剂，Ｃｕ（Ｉ）作催化剂，以醋酸、乙醇作为交换的介质。在一定条件下标记，标记率大于９７％。稳定性跟踪实验说明，在室温下，一周内产品仍可满足临床使用要求。更多还原

【Abstract】 A new rapid method of ￣（131）I labelled MIBG（Metaiodobenzylguanidine）was described.The la belling efficiency is more than 97%using Cu（Ac）₂ as a catalyst,acetic acid,alcohol system as a medium of exchange reaction under the certain labelling conditions.The stability of labelled ￣（131）I-MIBG cansatify the requirement of clinical application under the room temperature in a week.更多还原
