Diffusion weighted imaging techniques can be used to non-invasively map white matter pathways in the brain. The use of these techniques is well established in neuroscience and neuroanatomy research and is increasingly being used in clinical neuroradiology practice. A good understanding of the underlying physics and magnetic resonance imaging sequences is required to exploit the strengths and recognise the limitations of these white matter mapping techniques. Additionally, sound anatomical knowledge of white matter pathways is needed to accurately interpret such imaging with clinical relevance. This presentation will cover a number of white matter mapping techniques and show how they can demonstrate white matter anatomy through clinical cases.
