Brain tumors and difusion tensor imaging

Check out the latest concepts in delineation of spread of gliomas in the article : "Gliomas: Histopathologic Evaluation of Changes in Directionality and Magnitude of Water Diffusion at Diffusion-Tensor MR Imaging" by Andreas Stadlbauer et al in the latest edition of Radiology 2006;240 803-810, also available online at

The article describes how fractional anisotropy is better than mean diffusivity for assessment and delineation of different degrees of pathologic changes (ie, tumor infiltration) in glioma.
