Summary

In this study, we comprehensively evaluated the clinical utility of Trop2 PET/CT (68Ga-MY6349 PET/CT) imaging for detecting recurrent and metastatic thyroid cancer, and the results were compared with those of 68Ga-FAPI PET/CT. The primary objective of this study was to evaluate the patient-based sensitivity of 68Ga-MY6349 PET/CT in detecting recurrent and metastatic thyroid cancer. The secondary objectives included its overall specificity, lesion-based diagnostic performance, comparative tumor uptake relative to 68Ga-FAPI PET/CT, and the impact on clinical management.

Compared the diagnostic performance of 68Ga-MY6349 PET/CT with 68Ga-FAPI PET/CT

Each subject receives a single intravenous injection of 68Ga-MY6349 and 68Ga-FAPI and undergoes PET/CT imaging within the specified time. For participants who were not radioiodine-refractory or who did not have MTC or ATC, DxWBS was conducted. Each participant received an intramuscular injection of rhTSH on two consecutive days, followed by the oral administration of 131I. DxWBS was performed 2 days after 131I administration
