Head-to-head comparison of 18F fluorodeoxyglucose PET/CT and 68GaGa-prostate specific membrane antigen-11 PET/CT in radioactive iodine refractory differentiated thyroid cancer
Head-to-head comparison of imaging techniques shows FDG PET/CT has higher lesion detection rates in RAIR-DTC, while PSMA-11 PET/CT may indicate theranostic options.
Key Points
[18F]FDG PET/CT detected significantly more lesions than [68Ga]Ga-PSMA-11 PET/CT, especially in lymph nodes and lungs.
[18F]FDG PET/CT achieved a lesion detection rate of 96.8%, compared to 60.1% for [68Ga]Ga-PSMA-11 PET/CT.
