FIG 2. A–F, Scatterplots show initial lesion volume versus final infarct volume in patients with a perfusion-diffusion mismatch (perfusion lesion more than 20% larger than the diffusion lesion).
A and B, DW-CBV mismatch group: For DW imaging versus follow-up, the regression line was significantly different from the line of identity (P < .001). For CBV versus follow-up, the regression line was not significantly different from the line of identity (P = .18).
C and D, DW-CBF mismatch group: For DW imaging versus follow-up and for CBF versus follow-up, the line of regression was significantly different from the line of identity (P < .001).
E and F, DW-MTT mismatch group: For DW imaging versus follow-up and for MTT versus follow-up, the line of regression was significantly different from the line of identity (P < .001). r2 indicates coefficient of determination.
