This area is likely to correspond to a bone marrow-confined metastasis not yet characterized by bone remodeling and thus falsely negative in both multidetector computed tomography and ¹⁸F-sodium positron emission tomography/computed tomography. No structural lesions or area of ¹⁸F-NaF uptake are evident in the vertebral column of this breast cancer patient (A); by contrast an area of high focal ¹⁸F-FDG uptake was present in the sixth dorsal vertebra (B). ¹⁸F-NaF: ¹⁸F-sodium; ¹⁸F-FDG: 2-deoxy-2-(¹⁸F)fluoro-D-glucose.
