The differences between groups are significant (P < .0001, Kruskal-Wallis Test). Normal versus osteopenia, P = .026; normal versus osteoporosis, P < .0001; osteopenia versus osteoporosis, P = .077 (Mann-Whitney U test). B, Graph of diffusion signal-intensity values for normal, osteopenic, and osteoporotic subjects. The differences between groups are significant (P < .0001, Kruskal-Wallis test). Normal versus osteopenia, P = .004; normal versus osteoporosis, P < .0001; osteopenia versus osteoporosis, P < .0001 (Mann-Whitney U test).
