MR Physics & Techniques for Clinicians (3)
Weekday Course

ORGANIZERS: Bernd Jung, Marcus Alley, Dong-Hyun Kim

Wednesday, 15 May 2019
Room 710A  15:45 - 17:45 Moderators:  Dosik Hwang, Geon-Ho Jahng

Skill Level: Basic to Intermediate

Session Number: W-01

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 "hows" and "whys" 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
As a result of attending this course, participants should be able to:
- Define and describe the fundamental principles of MR imaging including the definition of spin magnetization;
- Explain the Larmor relationship, relaxation phenomena, and the process of using the spin magnetization to produce an image; and
- Describe how changing acquisition parameters impacts on the image quality and understand the parameter relationships.


  MR Angiography

  Parallel Imaging
Martin Blaimer
In recent years, parallel imaging techniques have become essential tools for accelerating MRI exams. Nowadays, basically all modern MR systems are equipped with multi-channel coil arrays and dedicated reconstruction algorithms. After a short historical overview, this talk will describe the basic concepts of parallel imaging. Limitations due to noise amplification (i.e. g-factor) and reconstruction artifacts will be discussed and applications will be presented. Finally, future perspectives (e.g. extensions with compressed sensing or machine learning) will be outlined.
