Background: Serum thyroglobulin (Tg) is a useful marker of recurrent or persistent disease in the follow-up of patients with differentiated thyroid carcinoma (DTC); the presence of interfering Tg antibodies (TgAb), even in low concentrations, can lead to a distorted evaluation of this marker. However, TgAb by itself has been shown to be a marker of disease following surgery. TgAb recognition of Tg epitopes differs in pathological and non-pathological states and may thus have p...

Background: Fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET) is a new method employed in the management of differentiated thyroid cancer (DTC). The integrated FDG-PET plus computed tomography (PET/CT) fusion imaging system seems able to provide some additional advantages over PET alone, mainly related to a better anatomical localisation of the hypermetabolic metastatic lesions. The influence of serum TSH levels on 18F-FDG uptake by recurrences o...
