Educational Session: MR Physics & Techniques for Clinicians

Educational Course

ORGANIZERS: Marcus T. Alley, Ph.D. & Bernd Jung, Ph.D.

Monday, 24 April 2017
Room 316BC  16:15 - 18:15 Moderators: Marcus Alley, Oliver Wieben

Skill Level: Basic to Intermediate

Slack Channel: #e_crosscutting
Session Number: M02


Overview
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 image quality.

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;
-Recall the Larmor relationship, relaxation phenomena, and the process of using the spin magnetization to produce an image; and
-Relate how changing acquisition parameters impacts on the image quality and explain the parameter relationships.

Spin Gymnastics
Walter Kucharczyk
This is non-mathematical overview of how MRI signals are generated, received, and encoded to form magnetic resonance images.

17:35
Image quality - permission withheld
Rafael O'Halloran
We will take a graphical approach to explore key concepts of image quality and discuss how sequence parameters affect image quality using the idea of k-space. 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.
