MTR, ADC, and FA values in cerebral white matter of 14 healthy control subjects (in vivo) and in 5 postmortem control brains immediately after postmortem (fresh) and after formalin fixation (fixed)
| In Vivo (mean) | Postmortem, Fresh (mean) | Postmortem, Fixed (mean) | |
|---|---|---|---|
| MTR (%) | 32.0 ± 1.5 | 30.6 ± 0.8 | 25.0 ± 0.5a |
| ADC (10−3 mm2/s) | 0.80 ± 0.07 | 0.25 ± 0.06a | 0.18 ± 0.05a |
| FA | 0.43 ± 0.02 | 0.22 ± 0.05a | 0.37 ± 0.04 |
