Abstract:
A 77-year-old woman with recently diagnosed breast cancer underwent 68 Ga-labeled DOTA-ibandronic acid ( 68 Ga-DOTA-IBA) PET/CT scan for the evaluation of bone metastases. The examination revealed increased tracer uptake, indicating that the cervical vertebrae presented osteoblastic metastasis. Interestingly, the breast cancer also showed enhanced activity of 68 Ga-DOTA-IBA.
