[Somatostatin receptor PET/CT (SSTR-PET/CT)]

The present guideline is focused on quality assurance of somatostatin receptor PET/CT (SSTR-PET/CT) in oncology patients. The document has been developed by a multidisciplinary board of specialists providing consensus of definitions, prerequisites, methodology, operating procedures, assessment, and standardized reporting. In particular, imaging procedures for the two most commonly used radioligands of human SSTR, i. e. 68Ga-DOTATOC and 68Ga-DOTATATE are presented. Overall, SSTR-PET/CT requires close interdisciplinary communication and cooperation of referring and executing medical disciplines, taking into account existing guidelines and recommendations of the European and German medical societies, including the European Association of Nuclear Medicine (EANM), German Society for Endocrinology (DGE), German Society for Nuclear Medicine (DGN) and German Society for Radiology (DRG).
