Edema and right ventricle’s volume (affected hemisphere). The edema region was measured in each time point in the T2 maps, the region of high intensity T2 was measured in all slices (a). Quantitative data of edema’s volume (b) and right ventricle’s volume (c) is shown in each rat at each time point in one representative MRI slice. One day after tMCAO (TP1), two weeks after the first treatment (TP2), 1 month after the first treatment (TP3), one month after the final treatment session (TP4). M1 is a group receiving sham treatment, M2 was exposed to 3.93 Hz, and M3 was exposed to 15.72 Hz VLIFE 2 min sessions, in alternate days, for a month and followed up for an additional month.
