Comparison of NaF uptake according to diverse location and MRI protocol. When comparing NaF uptake in different brain areas and organs between the patients with and without diffusion positive lesions, its uptake intensity was not significantly different in the non-infarcted regions, such as pons (0.20 [0.20–0.30] versus 0.30 [0.20–0.30], p = 0.71, Mann–Whitney U test, A), cerebellum (0.20 [0.20–0.25] versus 0.30 [0.25–0.35], p = 0.16, Mann–Whitney U test, B), lumbar vertebrae (3.17 [2.50–3.38] versus 3.44 [3.31–3.57], p = 0.19, Mann–Whitney U test, C) or spleen (0.63 [0.51–0.71] versus 0.59 [0.53–0.65], p = 0.79, Mann–Whitney U test, D). The NaF uptake was not significantly different in the SWI ( +) lesions (2.50 [1.40–3.60] versus 0.85 [0.30–1.70], p = 0.64, Mann–Whitney U test, E) or FLAIR ( +) lesions (1.25 [0.40–2.50] versus 0.40 [0.15–1.45], p = 0.39, Mann–Whitney U test, F).
