Medullary Thyroid Carcinoma: An Update on Imaging

Figure 6

Mapping of the metastatic lymph nodes in medullary thyroid carcinoma. Asymptomatic patient after thyroidectomy for medullary thyroid carcinoma and elevated calcitonin level (54 pg/ml) was evaluated for possible neck lymph node metastases. Ultrasound of the neck showed several suspicious lymph nodes (not shown). One of the lymph nodes (b) was found to be positive on only 18F-FDOPA-PET/CT (c), while 18F-FDG-PET/CT and 68Ga-DOTATATE-PET/CT were negative.
