Synopsis
Keywords: Contrast mechanisms: fMRI, Neuro: Brain function
In this lecture, we’ll learn about the physiological and biophysical processes underlying functional MRI (fMRI), the pulse sequences used to perform fMRI, and example applications in clinical imaging and research.
After attending the session, attendees will be able to:
- Understand how brain physiology (blood flow and metabolism) is closely linked to neuronal activity
- Understand the Blood Oxygenation Level-Dependent (BOLD) MRI contrast mechanism
- Understand the changes in brain physiology that give rise to the BOLD fMRI signal
- Understand common acquisition strategies for imaging the BOLD fMRI response
- Recognize typical fMRI experimental designs
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
