FDG PET/CT for the early prediction of RAI therapy response in patients with metastatic differentiated thyroid carcinoma

Abstract

The patient group with FDG uptake in metastatic DTC showed poor response to RAI therapy regardless of the degree of RAI uptake. Therefore, FDG PET/CT may help us identify the patients with radioiodine refractory DTC and establish an appropriate treatment strategy in the early period.
