Diagnostic Performance of 18F-FDG PET/CT in Papillary Thyroid Carcinoma with Negative 131I-WBS at first Postablation, Negative Tg and Progressively Increased TgAb Level

Abstract Differentiated thyroid cancer (DTC) patients with negative serum thyroglobulin (Tg), negative 131I whole–body scintigraphy (131I-WBS) at first post-ablation and progressively increased TgAb level are a relatively rare entity in the follow-up after total thyroidectomy and radioactive iodine...
