In this course, comprised of three lectures, practical aspects of deploying Magnetic Resonance Imaging will be discussed. The aim of this course is to help radiologists to better understand the basics of MRI, and why clinical MRI exams are structured the way that they are. A detailed understanding of MRI physics is not required. MRI is complex due to the large number of parameters that can be adjusted and the unexpected artifacts that can arise, especially in the presence of motion. Determining an appropriate protocol for a clinical question balances the need for contrast between healthy and diseased tissue, the speed of the individual sequences, exam length, and the incremental diagnosic utility provided by adding to the protocol. This course will tackle these questions by focusing on three topics: 1) image contrast, and how it is generated and used to discriminate different tissues; 2) image resolution and how it relates to data collection, and 3) common artifacts, their causes, and how to mitigate them.

Content Areas (Codes):
The following Content Areas will be printed on the certificate for this course:

• Physics and Basic Science
• Education
• Magnetic Resonance Imaging

Learning Objectives:

• Describe how differences in contrast can be induced by the selection of particular pulse sequence settings to differentiate tissues using MRI.
• Discuss how data collection in MRI is related to image resolution and scan time, and make practical tradeoffs between these factors.
• Describe several common artifacts encountered in MRI, what causes them, and how to mitigate them.

This enduring material is estimated to take 1 hour to complete.
