Educational Session: MR Physics & Techniques for Clinicians

Skill Level: Basic to Intermediate

Organizer: Marcus T. Alley, Ph.D., Brian Hargreaves, Ph.D., Michael Markl, Ph.D., Bernd Jung, Ph.D. & Nicole Seiberlich, Ph.D.

Wednesday 11 May 2016

This two-hour course will be a basic and comprehensive review of MRI physics and techniques. The presentations will be non-mathematical and suitable for clinicians and physicists new to the field. The course will cover advanced MRI techniques including ultra-fast imaging, parallel imaging and an overview of the types of artifacts that appear in MR imaging.

Target Audience
This course is primarily designed for the clinician who will benefit from an understanding of the "how’s and why’s" of MR imaging. While it requires no prior experience with MR, those with some familiarity and experience will also benefit. Those interested may include: radiologists and clinicians relatively new to MR imaging (including residents and fellows), experienced radiologists and clinicians wanting a refresher course in MR physics, and physicists and engineers wanting an introduction to the field.

Educational Objectives
Upon completion of this course, participants should be able to:

  • Undestand the principles of ultrafast MRI methods including echo planar techniques
  • Describe the principles and applications of parallel imaging for accelerated MR imaging; and
  • Understand common MR imaging artifacts, their causes and implement strategies to mitigate image artifacts.

Parallel Imaging
Katherine Wright1

The main objective of this presentation will be to provide an overview of parallel imaging techniques and how these methods can be best used in the clinical environment. This will include an overview of accelerated data acquisition and the resulting aliasing artifacts, and will continue to describe how coil sensitivities and parallel imaging reconstruction methods can be used to reconstruct undersampled data. Importantly, there will also be a brief review of clinical applications of parallel imaging.

Diffusion & Perfusion Weighted Imaging
Matthias Weigel1

This lecture will explain the two important and popular imaging concepts of diffusion weighted imaging (DWI) and perfusion weighted imaging (PWI). The underlying physics and fundamental properties will be explained in a pictorial way (with only a few easy mathematical equations that may be important to recognize or use). The clinical significance and potentials of the two methods are also discussed. At last, DWI and PWI are combined to establish the so-called diffusion-perfusion-mismatch-concept in (acute) ischemic stroke.
