Figure 4. Associations of Magnetization Transfer Ratios and Fractional anisotropy values with IR-based classifications.

Figure 4

4a) IR-based lesion classifications in relation to MTR values and 4b) Fractional anisotropy (FA) values. Regions were classified as NAWM, or as non-black/gray hole, PGH and PBH using IR and showed decreasing trends from NAWM to PBH (p < 0.001, for each using model clustering lesions within patients).
