Neuroendocrine Tumors (NETs) Somatostatin Receptors
NETs Nuclear Medicine Imaging (molecular imaging) Mainly SSTR2 Target Neuroendocrine Tumors expressing somatostatin receptors Somatostatin Analogs Scintigraphy, SPECT, SPECT/CT with 111 In-Octreoscan PET/CT con 68 Ga-DOTATOC 68 Ga-DOTANOC 68 Ga-DOTATATE

Metastatic GEP-NET 111In-Octreoscan 68 Ga-Dotatoc PET/CT
CONCLUSION 68Ga-DOTATOC and 68Ga-DOTATATE possess a comparable diagnostic value in the detection of lesions of NETs
68Ga-DOTANOC PET/CT Physiological uptake in the uncinate process of pancreatic head Pathological uptake in the uncinate process of pancreatic head
Any visible focal tracer uptake in the pancreas must be considered as suspicious for malignancy irrespective of quantitative parameters. Therefore, follow-up with 68Gasstr-PET/CT is mandatory in the clinical setting if uptake in the head/uncinate process is observed.

Nuclear medicine procedures We recommend the use of SSTR functional imaging for localization and staging of G1-G2 GEP-NENs We recommend PET/CT with 68 Ga-labeled SA as the procedure of choice. When not available, 111 In-pentetreotide (Octreoscan ) scintigraphy may be used We recommend against the routine use of 18 F-FDG PET/CT We suggest 18 F-FDG PET/CT for staging high grade (G3) and selected G2 GEP-NENs
