Abstract

A 61-year-old woman diagnosed with breast cancer and bone metastases underwent a 68 Ga-labeled DOTA-ibandronic acid ( 68 Ga-DOTA-IBA) PET/CT examination to evaluate the feasibility of 177 Lu-DOTA-IBA therapy. The 68 Ga-DOTA-IBA PET/CT scan revealed multiple bone metastases throughout the body. Incidentally, the uptake of 68 Ga-DOTA-IBA was increased in the left axillary lymph node metastases and meningeal metastases.
