Spinal cord quantitative maps in an example slice. qMT parameter maps are shown in (a) both for uniform (top row) and optimized (bottom row) protocols, together with the shared T₁ maps estimated from the Inversion Recovery protocol. For the same slice, reproducibility indices I of model parameters are shown in (b). Reproducibility index I for a given parameter p is calculated from the three repeated acquisition using Eq. (5) and ranges between [0,1] (the higher, the more reproducible the metric is). More examples of qMT parameter maps and reproducibility indices I are given in Supporting Figures S5 and S6.
