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.

Monday 09 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 the basic principles of MR physics (signal generation, encoding, and relaxation) and k-space.

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:

  • Define and describe the fundamental principles of MR imaging including the definition of spin magnetization;
  • Understand the Larmor relationship, relaxation phenomena, and the process of using the spin magnetization to produce an image; and
  • Describe and understand the concept of k-space.

Moderators: Vikas Gulani, Bernd Jung
Spin Gymnastics - Permission Withheld
Walter Kucharczyk
Spin Gymnastics is both an introduction to MRI physics and a summary of its most important concepts. It is intended to "set the table" for a series of subsequent lectures in the Physics for Clinicians Course that build on the basic concepts presented in this lecture. The information is presented in a graphical, animated format to assist in the complex understanding of the spatial and temporal components of the MR imaging process.

We will take a graphical approach to review key concepts of k-space as they relate to MRI image quality. Using cartoons and images we will demonstrate how resolution, field-of-view, and SNR can be understood in terms of k-space coverage and sampling. The implications on image quality will be discussed and demonstrated with example images.
