The Added Clinical Value of 18F-FDG PET/CT in Evaluating Intratracheal Recurrence of Differentiated Thyroid Carcinoma: Implications for Planning Surgery, Assessing Its Completeness, and Planning Radioiodine Therapy

In selected patients with differentiated thyroid carcinoma, 18 FFDG PET/CT has been shown to have added value. We present 2 clinical examples in the settings of both iodine-concentrating and non–iodine-concentrating lesions with tracheal involvement with special reference to its importance in planning of surgery or radioiodine therapy and assessing completeness of surgery. We believe that the use of PET/CT should be considered on a case-by-case basis and specifically when SPECT/CT is un
