Axial non-contrast CT and PET-CT images for a 62-year-old male patient with history of prostate cancer for which he had chemotherapy and radiotherapy. Images a and b (baseline study) showed focal prostatic 68Ga-PSMA activity with SUVmax = 9.2 denoting residual neoplastic lesion that showed activity regression in images c and d (follow up study) showing SUVmax = 3.4 (red arrows). Images e and f (baseline study) showed metastatic low-grade 68Ga-PSMA activity by subcentimetric right external iliac lymph node with SUVmax = 3.5 and showed activity regression in images g and h (follow up study) with SUVmax = 1.7 (blue arrows). Images i and j (baseline study) showed small right femoral neck sclerotic lesion with minimal 68Ga-PSMA activity that was considered insignificant, yet it showed activity progression in images k and l (follow up study) with SUVmax = 9.6 (green arrows)
