Skill Level: Basic to Intermediate

Session Number: M-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:
- 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;
- Analyze the concept of k-space; and
- Describe the basic hardware components of an MRI scanner and the function of each.

		Spin Gymnastics Walter Kucharczyk Watch the Video The physics of MRI will be reviewed with the goal of presenting an intuitive and graphically centered conceptual framework. The lecture is given in two components; the physics of NMR followed by the principles of MR imaging. Throughout the lecture, unique 3D animations are used to illustrate complex concepts in a graphically intuitive manner. The overall goal is to provide a working knowledge of the basic physics of MRI in a way that is both intuitive and true to the physics of MRI.
		k-Space & Image Quality Walter Witschey Watch the Video
		Basic MRI Hardware Components Martijn Cloos Watch the Video This lecture will cover the basic hardware components found in an MRI system. Imagine it is 1972 and you just had a wonder full idea. Employing principles from NMR, you plan to “form images through local interactions”. As you arrive in the lab you immediately start discussions with the engineering team to build such a system. We will use these imagined discussions to better understand the functional role and design constrains of the basic components found in modern day MRI systems. Although some essential MR physics will be covered in passing, basic familiarity with the MRI process is assumed.
