This paper extensively discusses the topic of neuroendocrine tumors and the application of somatostatin receptor scintigraphy as a key imaging diagnostic method for their diagnosis and monitoring. Neuroendocrine tumors are rare types of tumors, but their incidence is steadily increasing worldwide. These tumors can develop in various parts of the body and contain significant concentrations of somatostatin receptors. Thanks to somatostatin receptor scintigraphy, it is now possible to detect neuroendocrine tumors that may not have been visible using other diagnostic methods, and due to its high sensitivity, it has become one of the most common nuclear medicine methods for detecting and diagnosing neuroendocrine tumors. The aim of this study was to investigate the role of somatostatin receptor scintigraphy in the evaluation of neuroendocrine tumors at the Clinical Hospital Center Split. The study included a total of 73 patients, and all data were collected at the Department of Nuclear Medicine of the Clinical Hospital Center Split. Parameters such as gender, age of patients, measured chromogranin A levels, and the presence of pathological accumulation of radiotracer were considered. For the purpose of analysis, the collected patient data were statistically processed and presented through tables and figures. The study involved a significantly higher number of females (60%) than males (40%), with an average age of 63.58 years. The research results reveal significant statistical differences in the values of pathological radiopharmaceutical accumulation based on gender and age of the patients, as well as in the values of chromogranin A concerning the patients' age group. This study provides valuable insights into the importance of the used parameters in diagnosing neuroendocrine tumors and confirms the crucial role of somatostatin receptor scintigraphy in timely identification and monitoring of these tumors.
