      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.

      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.

      Boxers and mixed martial arts athletes underwent brain DTI and the results were correlated with number of fights, knockouts, age, weight, and years of education. Total knockouts in boxers increased diffusivity in the corpus callosum, cingulate, pericalcarine, precuneus, and amygdala, while in martial arts athletes only the posterior cingulate was abnormal. Thus, fight exposure but not the number of fights can be used to predict microstructural brain damage.

      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.

      The utility of MRS in differentiating lymphoma from tumefactive demyelination was assessed in 44 patients with the former and 21 with the latter. A Cho/Cr over 2.58 and a high lipid/lactate peak were more common in lymphoma, therefore MRS may help in differentiating these 2 entities.
