FIGURE 2. A 56-y-old woman with multiple liver and lymph node metastases was referred for restaging after surgery and chemotherapy. CT presented these tumor lesions; however, it was negative for bone lesions. Beside the visceral metastases, some additional osteoblastic and osteolytic bone metastases were clearly depicted with 68Ga-DOTA-TOC (A). Only some of these bone metastases were delineated by conventional scintigraphy (B, anterior view; C, posterior view). Osteoblastic bone lesions were confirmed by 18F-Na-fluoride PET (D). Retrospective CT analysis after image fusion revealed some of these bone metastases.
