Joint Annual Meeting ISMRM-ESMRMB 2014 10-16 May 2014 Milan, Italy

Everything You Wanted to Know about Magnetic Susceptibility & Why It Is Important
SKILL LEVEL: Basic to Intermediate
ORGANIZERS: Joseph J. H. Ackerman, Ph.D. & Jürgen R. Reichenbach, Ph.D.
Thursday, 15 May 2014
Magnetic-susceptibility-driven contrast is critically important in a variety of MRI protocols, yet the underlying fundamentals are often poorly understood. This course will present a tutorial on the origins of magnetic susceptibility, how it manifests in the MRI experiment, and how it can be leveraged to offer powerful and unique image contrast at high field and at clinically relevant fields.
Clinicians and basic researchers wishing to understand and apply the many MRI methods that leverage magnetic-susceptibility-driven contrast.

As a result of attending this course, participants should be able to:

  • Understand the molecular origins of bulk magnetic susceptibility and describe its effects on an externally applied magnetic field;
  • Understand the manner in which the magnetic resonance signal contains phase information and describe the manner in which magnetic susceptibility inclusions will affect the MR signal phase protocols that provide high sensitivity to magnetic susceptibility inhomogeneities;
  • Understand and describe MR pulse sequences that lead to MRI;
  • Recognize the advantages and limitations of high magnetic field strengths for MR susceptibility imaging and describe the information content of such images;
  • Recognize that high quality MR susceptibility imaging can be accomplished at 3T and describe the information content and possible clinical applications of such images; and
  • Assess the procedural and analysis challenges posed by MR susceptibility imaging and identify clinical areas to apply the technique in order to have most significant impact.
