Representative transversal slice images, from two patients (one per column). The left-hand column shows a lesion (red arrow, bottom image) suspicious for lymph node metastasis of prostate cancer that was detected by [89Zr]Zr-PSMA-617 PET/CT (48-hr scan shown here) but not [68Ga]Ga-PSMA-11 PET/CT (top image). As exemplified in the right-hand column, all lesions detected on [68Ga]Ga-PSMA-11 PET/CT also were detected on [89Zr]Zr-PSMA-617 PET/CT (lesions indicated by blue arrows)
