Fig. 6From: A pilot study of 68 Ga-PSMA-617 PET/CT imaging and 177Lu-EB-PSMA-617 radioligand therapy in patients with adenoid cystic carcinomaA 56-year-old male patient was diagnosed with local recurrence and multiple metastases 12 months after surgical removal of nasal ACC. Pre-therapy 68 Ga-PSMA-617 (A–D) and 18F-FDG PET/CT (I–L) depicted neoplasm recurrence, multiple liver, bone, and lung metastases. 68 Ga-PSMA-617 PET/CT (E–H) and 18F-FDG PET/CT (M–P) reexamination at 8 weeks after the 1st cycle of PSMA RLT revealed the decreased SUVmax of lung metastases (red arrow) and liver metastases (blue arrow); and CT showed liquefied necrosis occurred inside the lung nodule (red arrow). The uptakes of bone metastases (yellow arrow), however, were significantly increasedBack to article page
