The researchers reported, for example, that [68Ga]Ga-PSMA-11-PET was unable to differentiate TB from pulmonary metastases; however, performing [68Ga]Ga-alfatide II-PET/CT imaging in TB patients had much higher specificity than [18F]FDG when distinguishing TB from Non-Small Cell Lung Cancer. Here, FOLH1 is linked to tuberculosis.
