Man with biochemical relapse of prostate cancer (prostate-specific antigen [PSA] level, 2.68 ng/mL). A–C, CT (A), PET (B), and fused PET/CT (C) images show pathologically increased 11C-choline uptake in subcentimeter right external iliac lymph node. Pelvic lymph nodal area was irradiated with resultant decline in PSA to undetectable level at 3 months after completion of therapy regimen. (Reprinted with permission from [218])
