Abstract

This case report demonstrates the successful localization of metastatic medullary thyroid carcinoma with 99mTc-labeled methoxyisobutylnitrile (MIBI). Disease recurrence was initially localized using 201Tl and by immunoscintigraphy with 111In-labeled anti-carcinoembryonic antigen (anti-CEA) antibody fragments. Scintigraphy with 99mTc-MIBI yielded higher target-to-background ratios than 201Tl or 111In-anti-CEA. Technetium-99m-MIBI may be a useful agent in the localization of recurrent medullary thyroid carcinoma.
