Monitoring response to RLT with PET/CT ⁶⁸Ga-DOTATOC. Female, 58 years old, pNEN, G2, surgically removed in 2016. Staging before and after RLT with ¹⁷⁷Lu-Lutathera. PET/CT 68Ga-DOTATOC MIP (a) depicts the extent metastatic disease (thoracic, axillary and abdominal LNs, liver metastases) before RLT. (b) MIP after RLT with no evidence of liver metastases and abdominal lymph nodes along with a significant reduction in the radioligand uptake of thoracic lymph nodes, which is suggestive for a partial response.
