Effect of Peptide Receptor Radionuclide Therapy on Somatostatin Receptor Status and Glucose Metabolism in Neuroendocrine Tumors: Intraindividual Comparison of Ga-68 DOTANOC PET/CT and F-18 FDG PET/CT
Figure 2
Relationship between SUVmax before and after PRRNT. (a) Changes of SUV on 68Ga DOTANOC (SMS) PET/CT in response to PRRNT. The SMS uptake decreased significantly in both group A and group B; baseline SUVmax of group A was higher than that of group B. (b) SUV changes on 18F FDG (FDG) PET/CT in response to PRRNT. The FDG uptake decreased significantly in group A, whereas the uptake in group C increased. The baseline SUVmax of group C tended to be higher than that of group A. (c) The relationship between therapy response and baseline SUVmax of 68Ga DOTANOC PET/CT. The response is positively correlated with the baseline SUVmax.
