The paper deals with the topic of neuroendocrine tumors (NET) and imaging diagnostic connections for their diagnosis, especially scintigraphy of somatostatin receptors as a method of choice. Neuroendocrine tumors as a heterogeneous group of neoplasms pose a major challenge in diagnosis and treatment. The paper presents methods for the diagnosis of neuroendocrine tumors, with special attention paid to imaging medical modalities, whether the imaging procedures were classical or functional. Based on previous knowledge and literature review, data on the specifics and sensitivity of individual methods are shown and the procedures for obtaining images are explained. Nuclear medical tests are set as an imperative in the diagnosis and monitoring of NET. The goal of this study was to determine the role of somatostatin receptor scintigraphy in the detection of neuroendocrine tumors, their follow up and disease assessment, and also to determine the frequency and reasons for performing of this diagnostic test in the KBC Split. For the purposes of this paper, the documentation of KBC Split, Institute of Nuclear Medicine was collected retrospectively for the period from 1.1.2019. to 31.12.2020. Collected documentation shows data on 152 cases of performed somatostatin receptor scintigraphy. Statistical data processing and tabular and graphical structures show data on patients according to the observed characteristics. In the observed group, the representation of men is higher compared to women, with a mean age value of 65.50 years. A third of examinations performed were follow up scintigraphy examinations and the frequency of this exam due to disease staging or disease diagnosis was nearly equal. The most common location of the suspected primary lesion was the gastrointestinal tract (35,53%) and the most common location of pathological lesions on exam was the liver (50,88%). SPECT/CT was performed at every case of examination. A significant role of said examination in follow up of already diagnosed disease and its role in assessing therapy along with correctly diagnosing suspected neuroendocrine tumour was confirmed along with SPECT/CT as being an indispensable method due to improving diagnostic accuracy and better localization of lesions and differentiating between pathologic and physiologic or unspecific radiopharmaceutical uptake.
