Educational Course
MR Physics & Techniques for Clinicians
MR Physics & Techniques for Clinicians
Weekday Course

ORGANIZERS: Marcus Alley, Bernd Jung

 
Tuesday, 19 June 2018
S01  16:15 - 18:15 Moderators:  Bernd Jung, Matthias Weigel

Skill Level: Basic to Intermediate

Session Number: Tu-01

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 "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:
-Describe the basic physics and properties of pulse sequences based upon spin and gradient echoes;
-Explain fast spin-echo imaging and applications of basic MR pulse sequences; and
-Design MR imaging protocols for diagnostic applications considering image contrast, spatial resolution, acquisition time, signal-to-noise ratio, and artifacts.

Armin Michael Nagel
Magnetic resonance imaging (MRI) techniques can usually be classified into spin-echo (SE) and gradient-echo (GRE) pulse sequences. In this presentation, the basic physical principles of GRE imaging, as well as different mechanisms to generate image contrast will be explained. Differences between SE and GRE MRI will be discussed. Additionally, the influence of different pulse sequence parameters (e.g. echo time, repetition time, flip angle; as well as spoiling techniques and preparation pulses) on the image contrast will be covered. Clinical applications of GRE imaging techniques will be shown exemplarily.
