Estimating CSF temperature in the lateral ventricles of a human volunteer using. (a) Uncorrected temperature map showing artificially high temperatures within the lateral ventricles because of outliers and artificially low temperature estimates for brain tissue due to restricted diffusion. (b) Display of all the 32 diffusion constant estimates from six representative voxels (marked with white squares in (a). The asterisks represent the nine directions found to be least prone to artefacts. (c) Temperature map where only the directions marked on panel (b) were averaged for each voxel within the lateral ventricles. The mean estimated temperature within the lateral ventricles is 37.9 °C in this slice.
