Abstract
We presented a case involving a 56-year-old man who had been experiencing shoulder and back pain for over a year, with extensive bone metastases revealed by a bone scan. To identify the primary source of these issues, the patients underwent a fluorine-18-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) scan, which indicated moderate uptake in the right renal soft mass and low uptake in multiple osteolytic lesions. Pathological examination and immunohistochemical staining of the renal mass supported the diagnosis of neuroendocrine tumors. Subsequently, a novel somatostatin receptor imaging agent, Al18F-NOTA-octreotide (18F-OC), was performed to further investigate the source of metastatic lesions and to stage the tumor. The 18F-OC scan revealed a high-uptake lesion in the pancreatic head, as well as additional lymph node and bone metastases lesions.Compared to 18F-FDG, the 18F-OC demonstrated superior imaging capabilities and a significantly higher tumor-to-background ratio in neuroendocrine neoplasms, which contributed to improvingthe staging and treatment management.
期刊介绍:
The Hellenic Journal of Nuclear Medicine published by the Hellenic Society of
Nuclear Medicine in Thessaloniki, aims to contribute to research, to education and
cover the scientific and professional interests of physicians, in the field of nuclear
medicine and in medicine in general. The journal may publish papers of nuclear
medicine and also papers that refer to related subjects as dosimetry, computer science,
targeting of gene expression, radioimmunoassay, radiation protection, biology, cell
trafficking, related historical brief reviews and other related subjects. Original papers
are preferred. The journal may after special agreement publish supplements covering
important subjects, dully reviewed and subscripted separately.
