Synopsis
Keywords: Contrast mechanisms: Diffusion, Neuro: Brain connectivity
In this lecture, we’ll learn about the physiological and biophysical processes underlying diffusion MRI, the pulse sequences used to image diffusion, and example applications in clinical imaging and research.
After attending the session, attendees will be able to:
- Understand how tissue structure impacts the random diffusion of water molecules
- Understand common acquisition strategies for imaging water diffusion and the typical images that are generated
- Understand how brain pathology can impact diffusion images
- Understand how diffusion MRI can be applied in “tractography” for mapping structural brain connectivity
Introduction
The 2023 ISMRT Master Class series focuses on “The Basics of Advanced Brain Imaging”. Functional MRI (lecture 1), Diffusion MRI (lecture 2), and Perfusion MRI (lecture 3) are core techniques used in brain research, and all have been adopted clinically. In these lectures, we’ll learn about the physiological and biophysical processes underlying each contrast mechanism, the pulse sequences used to image the contrast, and example applications in clinical imaging and research.Learning Objectives
