Bone marrow fat content and composition by MR-spectroscopy (MRS)
| BONE MARROW FAT (by MR-Spectroscopy) | Co (n=17) | Fx (n=19) | DM (n=16) | DMFx (n=17) |
|---|---|---|---|---|
| Total Bone Marrow Fat Content (%) | 71.7 ± 2.2 | 65.1 ± 2.1 | 70.7 ± 2.5 | 69.4 ± 2.4 |
| Bone Marrow Fat Unsaturation (%) | 7.4 ± 0.5 | 6.1 ± 0.5 | 6.4 ± 0.6 | 4.3 ± 0.6a,c |
| Bone Marrow Fat Saturation (%) | 75.3 ± 1.1 | 78.2 ± 1.2 | 79.2 ± 1.0a | 82.0 ± 1.1a |
| Residual Bone Marrow Lipids (%) | 17.3 ± 0.7 | 15.7 ± 0.8 | 14.4 ± 0.7a | 13.7 ± 0.7a |
Data are averaged for L1-L3, means are adjusted for age, race, spine BMD by QCT ± SEM. Boldface indicates significant differences.
