Overview

Diffusion Magnetic Resonance (MR) is ubiquitous in various fields including biomedicine, battery research and petroleum industry and may reveal novel characteristics of the underlying systems in a non-invasive manner. Molecular diffusion is a stochastic process and the molecular diffusion coefficient reflects on the ability of the molecules to “travel” over distances . Fortunately, the length scale , typically of the order of a few microns, is accessible with conventional MR machines. In this webinar we will be focusing on how diffusion MR may be used various fields and introduce its basic concepts.

What to expect

We will first introduce the rich physics of diffusion and connect its fundamental principles to the Magnetic Resonance methodology. Illustrative examples such as Spin Echo NMR will make the introduction to diffusion MR, followed by more sophisticated methods, such as diffusion tensor imaging (DTI), that may help visualize the human brain tracts. In addition, applications of in-vivo and ex-vivo diffusion MRI, diffusion NMR in porous media and batteries will be presented.

Key points

  • Diffusion process – Gaussian and non-Gaussian Diffusion
  • iffusion Magnetic Resonance – What do we measure with MR?
  • Diffusion Tensor Imaging
  • Diffusion and Microimaging instrumentation
  • Restricted diffusion in porous systems
  • Diffusion MRI in the brain and spinal cord
  • Exotic Cases

Who should attend?

This webinar will be especially useful for NMR-MRI users working on diffusion and microimaging techniques. The first part of the webinar namely, “Diffusion Basics”, will be particularly relevant for those who need an overview of the physics of diffusion, as this introduction will glimpse through the salient concepts of transport. The second part will give the attendees an overview of what is achievable with diffusion MR techniques.
