• Second minor concern is the description of the acquisition sequences - in the section 3.1 you should specify the type of sequence used (MP-RAGE) and the units of measurements (ms). Also, this section should describe acquisition parameters of the MS cohort (currently described in section 3.3)

We have added units to tables 1-4 to be more precise (ms for TR, TE and TI, mm for FOV and voxel size, degrees \(^\circ\) for the flip angle, and T for the field strength). We also moved the description of the 3D-FLASH sequence acquisition parameters to the acquisition section of 3.1, and specified that all images were T1-weighted 3D-MPRAGE sequences.
