Axial non-contrast CT and PET-CT images for a 61-year-old male patient with history of prostate cancer for which he had radiotherapy and hormonal therapy. Images a and b showed focal prostatic 68Ga-PSMA activity with SUVmax = 4.7 (red arrows) denoting residual neoplastic lesion. Images ad showed marked 68Ga-PSMA activity by metastatic left iliac nodal mass lesion encroaching on the left obturator and sacro-sciatic foramina with SUVmax = 50.1 (blue arrows). Images e and f showed marked 68Ga-PSMA activity by metastatic osseous lesions involving the right inferior pubic ramus and both proximal femora, the most active shows SUVmax = 45.4 (green arrows) with no gross corresponding CT findings
