Supplementary Material

These videos show the diffusion and perfusion lesions as they deform in space and time and visualize the different expanding areas in both lesions. Video 1 displays the estimated spatiotemporal evolution scenario of MTT lesion (in red) and DWI lesion (in blue) from acute to subacute timepoints (video 1). Videos 2 and 3 are dynamic translations of Figure 5 (see manuscript): in video 2 you can see the “lighting up” process of successively highly expanding DWI regions along the evolution process, all visualized on the baseline surface at the first acquisition timepoint t1; and in video 3 you can see consecutively highly expanding MTT regions “lighting up” from acute to subacute stages, all mapped back into the baseline MTT lesion surface acquired at timepoint t1.
