FIG 1. A–D, Scatterplots demonstrate initial lesion volume with each technique versus final lesion volume at follow-up (F-U) in 81 patients.
A, Initial DW imaging versus follow-up: r2 = 0.9, slope = 1 .24 ± 0.08 (95% confidence limits).
B, Initial CBV versus follow-up: r2 = 0.84, slope = 1 .22 ± 0.11.
C, Initial CBF versus follow-up: r2 = 0.35, slope = 0.44 ± 0.09.
D, Initial MTT versus follow-up: r2 = 0.22, slope = 0.32 ± 0.08.
r2 indicates coefficient of determination.
