Webb19 nov. 2010 · Significant tonsil uptake is sometimes observed in F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) after treatment. Some patients undergo tonsillectomy or FNA (fine needle aspiration) to rule out malignant involvement particularly when management depends on restaging ( Figure 1 ). WebbOn PET scans, the thyroid gland exhibits very low physiologic FDG avidity. However this is typically less than the background blood pool and is usually not clearly visualized on the whole-body fusion PET/CT images [ 5 ] , which aligns with the observation that the primary energy substrate for the thyroid is free fatty acids [ 20 , 21 ] .
