In the field of neuromuscular disorders, muscle water T2 measurement is proposed as a marker of disease progression. However in case of fat infiltrated muscle since T2 values are higher in fat than in water, mono-exponential fits of non-fat-suppressed echo trains will result in T2 values that principally reflect the degree of fat infiltration. Yet fat-suppression often fails over large volumes.
