Fig. 1 (A, C) A 60-yr-old patient with Gleason 9 prostate cancer (PCa) after radical prostatectomy (RP) and external-beam radiation therapy (EBRT); actual prostate-specific antigen (PSA) was 3.04 ng/ml. (a, arrows) Axial T2-weighted magnetic resonance imaging (MRI) of the pelvis showing normal-sized, nonsuspicious iliac lymph nodes. (C, arrows) Corresponding gallium 68 (68Ga) prostate-specific membrane antigen (PSMA) positron emission tomography (PET)/MRI fusion demonstrates 68Ga-PSMA tracer accumulation, representing lymph node metastases. (B, D) A 60-yr-old patient after EBRT and androgen-deprivation therapy; actual PSA was 63 ng/ml. (B, arrow) Axial T2-weighted MRI of the pelvis depicts a slightly hypointense lesion in the anterior column of the right acetabulum. (D, arrow) 68Ga-PSMA PET/MRI fusion image in identical orientation reveals a high tracer accumulation, representing a bone metastasis. Note physiologic tracer accumulation in the bladder lumen and urethra.
