Technological advances in MR imaging and expanded clinical applications have drawn radiologists' attention to 3D MRI volumetric techniques and are dazzling them with the possibilities.

Tensor imaging and tractography are diffusion-based MR techniques for advanced functional imaging of brain white matter.1 Imaging brain anisotropy can yield useful information about white matter integrity and demonstrate pathology occult to conventional imaging techniques. Anisotropy imaging can also provide information about ordered white matter (WM) tracts such as directional orientation and connectivity, which can be critical in surgical planning and useful in the understanding of certain developmental and acquired disease states.
