Representative transversal slice images, from 3 different patients (one per column) showing lesions (indicated by green arrows), that were indeterminate on [68Ga]Ga-PSMA-11 PET/CT (top row) but could be visually classified as non-suspicious (negative) for prostate cancer on [89Zr]Zr-PSMA-617 images (48-hr scan shown here). The lesions indeterminate on [68Ga]Ga-PSMA-11 PET/CT were considered possibly suspicious for local recurrence, lymph node metastasis, and bone marrow metastasis, respectively (left to right), of prostate cancer
