Correlation between Calcitonin Levels and [^𝟏𝟖F]FDG-PET/CT in the Detection of Recurrence in Patients with Sporadic and Hereditary Medullary Thyroid Cancer

Figure 2

[¹⁸F]FDG-PET/CT images in a 40-year-old man with known familial MTC and calcitonin level of 6000 pg/mL, about 4 years after the initial treatment. Images show increased uptake of ¹⁸FDG in the right side of thyroid bed (SUVmax: 4.6) and in prevascular lymph nodes, in the mediastinum. The scan was proved true-positive as there was histological confirmation.
