Table 2.
The total volumes and volume fractions for the spatially normalized healthy control group and spatially normalized MS group of Figures 4 and 5 as well as for the three individual subjects of Figure 6.
| MYV (mL) | CV (mL) | FWV (mL) | EPWV (mL) | BPV (mL) | ICV (mL) | MYF (%) | CF (%) | EPWF (%) | |
|---|---|---|---|---|---|---|---|---|---|
| Control | 157 | 934 | 65 | 57 | 1148 | 1213 | 13.7 | 81.4 | 5.0 |
| MS | 119 | 872 | 144 | 78 | 1069 | 1213 | 11.1 | 81.6 | 7.3 |
| 45 year | 155 | 911 | 117 | 24 | 1090 | 1207 | 14.2 | 83.6 | 2.2 |
| 72 year | 142 | 944 | 308 | 41 | 1127 | 1435 | 12.6 | 83.7 | 3.7 |
| 45 year-MS | 119 | 875 | 204 | 37 | 1031 | 1234 | 11.5 | 84.9 | 3.6 |
Listed are the total myelin volume (MYV), cellular volume (CV), free water volume (FWV), excess parenchymal water volume (EPWV), total brain volume (BPV), and intracranial volume (ICV). The volume components that constitute the brain were normalized on BPV, resulting in the myelin fraction (MYF), cellular fraction (CF), and excess parenchymal water fraction (EPWF) of the brain.
