This paper describes the development of a lyophilized cold kit of DOTA-[Tyr3]-Octreotide (DOTA-TOC) for instant compounding of 68Ga-DOTA-TOC, suitable for diagnosis of neuroendocrine tumors. The work involved formulation of DOTA-TOC kits, optimization of radiolabeling, quality control of 68Ga-DOTA-TOC and animal biodistribution studies. The prepared kits enable a reliable method for preparation of 68Ga-DOTA-TOC of high radiochemical purity and excellent stability. Availability of such kits along with 68Ge/68Ga generators is expected to stimulate the widespread use of 68Ga-DOTA-TOC in nuclear medicine practice in developing countries.
