In this study, to produce and develop a new diagnostic radiopharmaceutical for the imaging of tumors with overexpressed somatostatin receptor, the [113mIn]In-DOTATATE chemical compound was prepared in optimal conditions using an in-house generator, and its preclinical studies were performed. The final product was obtained with a radiochemical purity of nearly 99% (RTLC and HPLC) and a specific activity of 26.2×1015 Bq/mol. The investigation of the stability of the labeled compound showed a radiochemical purity of more than 96% for at least three hours in PBS buffer and human blood serum. The results of the biodistribution and image assessment of the [113mIn]In-DOTATATE chemical compound in normal mice showed that the organs of the gastrointestinal tract such as the pancreas, stomach, and intestine, which have cells expressing the somatostatin receptor, have high uptake.
