Abstract
For localization of biochemical recurrence of prostate cancer, 68Ga-PSMA-11 PET/CT imaging was performed in a 66-year-old man with no suspicious findings at 1 hour p.i. Additional 89Zr-PSMA-617 PET/CT revealed a small local recurrence in the prostate bed, facilitating consecutive local therapy. This interesting image points to the potential of PET/CT with 89Zr-labeled PSMA ligands, for example, 89Zr-PSMA-617, for identifying the source of biochemical recurrence despite otherwise negative imaging including conventional PSMA PET/CT.
