Imaging Techniques for Metastatic Thyroid Medullary Cancer

ABSTRACT
Postoperatively elevated calcitonin levels strongly suggest the presence of residual or recurrent medullary thyroid carcinoma (MTC). Several imaging modalities including radiological and radionuclide techniques are often performed in patients with an elevated calcitonin levels until the tumor is localized. In this review, the major noninvasive imaging techniques and the advantages and disadvantages of each modality are discussed for metastatic MTC.
