The magnetization transfer ratio reflects the integrity of tissue structure, including myelination and axonal density. Mean magnetization transfer ratio fell in 18 untreated patients with multiple sclerosis both in normal appearing grey (-0.25 pu/year, p < 0.001) and white matter (-0.12 pu/year, p = 0.004). Conversely, mean magnetization transfer ratio ...
