      ASL was used to evaluate 54 children with recently diagnosed brain tumors using a pseudocontinuous technique and blood flow was calculated for all masses. Blood flow was higher in grade 3 and 4 tumors than in lower grade ones. Although ASL was unable to separate tumors by histology, perfusion was found to be higher in medulloblastomas than in pylocytic astrocytomas.

      Use of FLAIR Imaging to Identify Onset Time of Cerebral Ischemia in a Canine Model

      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.
