Imaging in thyroid cancer.

Abstract

No ideal imaging method is available for the diagnosis of MTC. Once the diagnosis is suspected, serum calcitonin or CEA may help to confirm it. Often, multiple studies are done, especially a combination of MR imaging or ultrasound and an isotopic method. Tc(V)DMSA is an excellent agent but not readily available in the United States. Indium-labeled pentreotide is probably the imaging agent of choice in the United States.
