FIG 2.

Post-treatment imaging for evaluation of response. A 70-year-old woman with pancreatic neuroendocrine tumor treated with two cycles of 177Lu-DOTATATE. (A) Pretreatment 68Ga-DOTATATE PET demonstrates SSTR-positive disease, with standardized uptake values up to 13.6. (B) Postcycle 1 planar gamma camera imaging demonstrates uptake in the osseous and hepatic disease (black arrowhead). (C) Postcycle 2 planar gamma camera imaging demonstrates increased uptake in the kidneys (black arrow) and significant reduction in uptake in the previously visualized disease consistent with response. PET, positron emission tomography; SSTR, somatostatin receptor.
