Figure 6. Dotatate-labeled selective somatostatin receptor (SSTR) positron emission tomography (PET) to evaluate primary tumor and metastases. (A) Axial cut of the PET scan showing increased uptake in the pancreatic head mass, corresponding to the biopsy-proven pancreatic neuroendocrine tumor. (B) Axial cut of the PET scan showing a very small focus of increased uptake in the right hepatic lobe. Metastatic disease cannot be excluded. (C) Coronal cut of the PET scan showing uptake in the pituitary gland; however, this may be physiologic.
