Purpose: To determine whether bone metabolic activity corresponds to bone and cartilage damage in patients with patellofemoral pain. Materials and Methods: We acquired magnetic resonance imaging (MRI) and 18 F‐NaF positron emission tomography (PET) / computed tomography (CT) scans of the knees of 22 subjects. We compared locations of increased tracer uptake on the 18 F‐NaF PET images to bone marrow edema and cartilage damage visualized on MRI. Results: We found that increased bone activity on 18 F‐NaF PET does not always correspond to structural damage in the bone or cartilage as seen on MRI. Conclusion: Our results suggest that 18 F‐NaF PET/CT may provide additional information in patellofemoral pain patients compared to MRI. J. Magn. Reson.
