68Ga-DOTANOC and 18F-FDG PET/CT in metastatic medullary thyroid carcinoma: novel correlations with tumoral biomarkers.

Metastatic disease is common in medullary thyroid carcinoma (MTC) and it is usually detected by raising calcitonin and carcinoembryonic antigen (CEA) levels. Nuclear medicine imaging has an important role in lesion identification/characterisation. We aim to compare 68Ga-DOTANOC PET/CT and 18F-FDG PET/CT performance and to explore the correlations between tumoral markers and functional imaging.
