(A) Baseline ⁶⁸Ga-PSMA PET/CT shows subcentimeter ⁶⁸Ga-PSMA–avid metastasis in right internal iliac lymph node (arrows). (B) Follow-up ⁶⁸Ga-PSMA PET/CT obtained 20 mo after metastasis-directed SABR shows complete local response, with PSA decline to 0.031 ng/mL. Shown are maximum-intensity projection images (rightmost and leftmost panels), axial CT images (upper middle panels), and axial PET/CT images (lower middle panels). RT = radiation therapy.
