Tuesday, 10 May 2022
N11 (Breakout B)
08:00 -  09:00
Moderators: Thomas O'Reilly & Leo Cheng
Skill Level: Basic to Intermediate
Session Number: S-Tu-07
 

Session Number: S-Tu-07

Overview
This course aims to explore the role and effects of static field strength (B0) on contrasts in various applications, particularly for B0 outside the range commonly used for clinical studies.

Target Audience
Clinicians, scientists, and engineers interested is using or developing MRI at particularly high (≥ 7 T) or low (≤ 1 T) fields.

Educational Objectives
As a result of attending this course, participants should be able to:
- Describe the physical principles that influence B0-dependent contrast(s);
- Identify potential clinical and research applications of low and high field MRI; and
- Discuss the trade-offs and limitations associated with low and high field MRI.

Contrast in MRI is obtained by leveraging the relaxation times of the different tissue species and can vary not only with the pathology/condition, but also with the static magnetic field strength (B0) of the MRI scanner. More specifically, it is known that T1 dispersion increases with decreasing B0. This point was overlooked for many decades but is now revived with the (re)growing interest of low-field MRI in the community. The potential added value of low-field MRI will be discussed and illustrated with various examples showcasing how low-field could complement the current MSK + Body imaging landscape.

Magnetic resonance imaging (MRI) at fields strengths ranging up to 3T is an imaging technique with a well-recognized clinical value. The benefits of MRI may be furtherly expanded with the adoption of ultra-high field (UHF) MRI. The push to explore increasing static field is the potential for an improved relative contrast between tissues and higher contrast-to-noise ratio (CNR). However, many of these benefits are frequently challenging to achieve and do not come without a price. Moreover, improved CNR do not necessarily lead to a clinical benefit.
