Figure 2. Example of the normalized qMRI reference maps in a slice through the brain.

The figure shows the reference maps obtained from images pooled across a group of 31 healthy subjects with A: R₁ relaxation rate on a scale 0–3 s⁻¹, B: R₂ relaxation rate on a scale 0–15 s⁻¹ and C: proton density on a scale 50–100%, where 100% corresponds to pure water at 37°C.
