Preoperative Diagnostic Value of [18F] Fluorodeoxyglucose Positron Emission Tomography in Patients With Radioiodine-Negative Recurrent Well-Differentiated Thyroid Carcinoma

Abstract

FDG-PET is a useful diagnostic tool in the follow-up of thyroidectomized patients with WDTC, negative (131)I scanning results, and abnormal serum thyroglobulin concentrations. The method detects metastatic disease in 94.6% of cases. PET results changed surgical tactics in a significant number of patients. Accurate staging of locoregional cancer recurrence in the neck may be consummately obtained by concomitant analysis of PET and ultrasound results.
