      After an infarction-inducing procedure, 20 dogs were imaged at 3, 4, 5, 6, and 24 hours with FLAIR and DWI. A mismatch between the 2 sequences (positive DWI and negative FLAIR) was found to reliably predict the time of infarct onset. By 6 hours, 95% of dogs had FLAIR abnormalities and by 24 hours all did. However, at 3 hours only 15% of dogs showed positive FLAIR studies. These results could serve as guidelines to estimate the time of onset of ischemic events.
