60 year old lady with a history of right breast cancer status post right brea1st lumpectomy, chemotherapy, radiotherapy and Femara. What is the most likely cause of the uptake in the ribs on this F18 NaF bone scan?
New abnormal tracer uptake is seen at the anterior ends of the right 7th and left 9th ribs.

NaF PET/CT is superior to Tc-99m MDP planar imaging. Clinical history is important for accurate image interpretation. Correlative imaging where available is often helpful. Clinical examination if possible may also contribute to accurate interpretation. In this case note the fracture on CT images that corresponds to the tracer uptake.
