Session Topic: Educational Q&A: P&E
Session Sub-Topic: Fundamentals of MRI Physics & Engineering II
Weekday Course
ORGANIZERS: Nicole Seiberlich, Michael Lustig, Elizabeth Hecht
Tuesday Parallel 1 Live Q&A Tuesday, 11 August 202015:15 - 16:00 UTC Moderators: Jesse Hamilton
Skill Level: Basic to Intermediate

Session Number: Tu-04

Overview
This session is part of an eight-hour course that will be a basic and comprehensive review of MRI physics and techniques; each session can be attended independent of the others. The presentations will be non-mathematical and suitable for clinicians and physicists new to the field and will cover topics including basic MRI physics, pulse sequence design, contrast weightings, image reconstruction, and image artifacts.

Target Audience
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:
- Explain the basic physics and properties of pulse sequences based upon spin and gradient echoes;
- Describe fast spin-echo imaging and applications of basic MR pulse sequences;
- Explain the principles of ultrafast MRI methods including echo planar techniques; and
- Describe the principles of perfusion imaging and diffusion-weighted imaging.

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.
