Overview
This course will provide an introduction to low-field MRI (<= 0.55T) with a strong focus on very low field (< 0.2T), as well as a description of today’s state of the research in these regimes. The course will discuss the different strategies (software and hardware) to maximize SNR for in vivo imaging and the various applications currently being explored.
Target Audience
Physicists, M.D.s, technicians interested in learning about low-field MRI and the opportunities it can offer.
Educational Objectives
As a result of attending this course, participants should be able to:
- Identify the opportunities and challenges to run MR experiments at very and ultra-low magnetic field strengths;
- Identify & explain sources of noise and how to mitigate them;
- Recognize current state-of-the-art clinical imaging in this regime.

08:10 | | New Opportunities for Endogenous Contrasts Lionel Broche Keywords: Physics & Engineering: Low-field MRI, Contrast mechanisms: Molecular imaging, Physics & Engineering: Physics Low magnetic fields are technically challenging to explore
but offer exciting new opportunities for clinical applications as they have a
high potential for safe, non-invasive and contrast agent-free examinations.
However, the strength of the magnetic field is critical when
relying purely on endogenous contrast, since different field regimes have
different types of information to offer. Low-field designs must therefore optimise
this parameter carefully.
This course will present different types of endogenous
contrast mechanisms that have been probed by Field-Cycling Imaging (FCI),
including T1 regimes and 14N quadrupolar peaks
cross-relaxation, and draw a picture of their variations with field strength. |

development of ultra-low-field (ULF) (<0.1T) and low-field (LF) (0.1-0.5T) MRI
technologies will enable patient-centric and site-agnostic MRI scanners to
fulfill the unmet clinical needs across various healthcare corners. This presentation aims to outline several approaches
to mitigate the MR signal reduction problem intrinsic to ULF (and LF) MRI. |
