Figure 3. Lesion overlays after stratification according to lesion volume (ischemic core volume tertials).

Lesion overlap based on magnetic resonance imaging data of 334 patients. Based on tertials of the ischemic core volume, the 3 groups are defined as small (A; <0.240 cc), medium (B; 0.240–2640 cc), or large (C; >2640 cc). Equidistant slices in Montreal Neurological Institute 152 standard space from z=32 to z=147.
