  • Note—ADC indicates apparent diffusion coefficient; NAA, N-acetylaspartate; rADC, ADC of lesion × 100/ADC of normal appearing white matter.

  • * Single voxel proton MR spectroscopy values expressed as a percentage calculated from the lesions in each time point, using the mean values obtained from the contralateral hemispheric normal appearing white matter as a reference.

  • Percentage of lesion volume within the proton MR spectroscopy voxel.
