  1. scan date 1 from the initial symptoms, scan date 2from the initial MRI. T2W T2-weighted image, T1WI T1-weighted image, Gd gadolinium enhancement, DWI diffusion weighted imaging, ADC apparent diffusion coefficient, DTI diffusion tensor imaging, SCC splenium of the corpus callosum, H high intensity, L low intensity, I isointensity, sH slight high intensity, sL slight low intensity, NE not examined
