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.
