From the abstract
68 Gallium NODAGA-JR11, a somatostatin receptor (SSTR) antagonist, exhibits superior sensitivity in detecting hepatic metastases of neuroendocrine tumors compared with the agonist tracer 68 Ga-DOTANOC PET/CT. In the presented case of rectal neuroendocrine tumor, both tracers identified the primary lesion and regional lymph node involvement; however, NODAGA-JR11 PET/CT revealed…
