| Résumé : | We report the case of a 69-year-old man with prostate cancer (PC), retroperitoneal lymph node metastases, and bone metastases, who received hormone therapy to date. The patient underwent a puncture biopsy in the third thoracic vertebra and was diagnosed with metastatic prostatic acinar adenocarcinoma with partly neuroendocrine differentiation. The patient underwent three different total-body PET/CT scans at ultra-low activities to evaluate tumor heterogeneity by multiple tracers (68Ga-PSMA PET/CT, 18F-FDG PET/CT, 68Ga-DOTA TATE PET/CT). Our case suggests that total-body PET imaging with 194-cm axial FOV using a 10*reduction in injected activity can yield images that meet diagnostic needs and that the results of multi-tracer analysis are encouraging for revealing the characteristics of each lesion. |
