68Ga-TCR-FAPI PET/CT Guided Precision Surgery for MTC
This is a phase II clinical trial to evaluate the capability of 68Ga-labeled targeted covalent radiopharmaceutical (TCR) fibroblast activation protein inhibitor (FAPI) PET/CT to guide the surgical treatment of medullary thyroid carcinoma (MTC). The surgical extent of MTC is determined based on the lesion range revealed by 68Ga-TCR-FAPI PET/CT, with the main endpoint being 1-month post-surgical calcitonin level.
