Radiotracer uptake in medullary carcinoma of the thyroid

Clin Nucl Med. 1980 Feb;5(2):45-8. doi: 10.1097/00003072-198002000-00001.


A patient with pathologically confirmed medullary carcinoma of the thyroid with lymph node metastases was noted to show uptake of radiothallium, radiopertechnetate, and radioiodine. A perchlorate washout test was markedly positive, indicating that the uptake was largely due to trapping.
