Figure 2 shows MTR simulations using the fundamental qMT parameters for four different tissues (Table 3; healthy cortical grey matter, healthy white matter, NAWM, early white matter multiple sclerosis lesion, late white matter multiple sclerosis lesion) using the four MT-weighted SPGR protocols from Table 2. \ No newline at end of file
