Overview
The underlying physics of magnetic resonance imaging is a topic of considerable importance since a basic understanding is necessary to accurately interpret and generate high quality MR images. Yet it can be a challenging topic in spite of the best efforts of both teachers and students of the subject. Practical MR Physics reviews the basic principles of MR using familiar language and explains the causes of common imaging artifacts and pitfalls. The book will also be a helpful guide during review of clinical cases since the reader can look up specific imaging artifacts or pitfalls in the index. Featuring over 375 high quality images, numerous case examples, and concise, clinically oriented discussion of the physics behind the images, Practical MR Physics is an ideal resource for anyone who works in the field of MR imaging.

Editorials
From The Critics
Reviewer: Donna M Reeve, MS(University of Texas M. D. Anderson Cancer Center)Description: This is primarily a collection of MRI cases selected to demonstrate the impact of MR artifacts on clinical images and their interpretation. A brief, nonmathematical introduction to principles of MRI in the first chapter is followed by presentation and discussion of numerous clinical examples of MR artifacts and pitfalls.
Purpose: The author uses cases to illustrate how an understanding of MR principles can help in the identification and understanding of common artifacts and in avoiding mistaking artifacts for disease. The cases provide excellent examples for achieving this goal and the author's explanations are clear and well written.
Audience: Since the focus of this book is the description of MR artifact appearance on clinical images and the potential impact on diagnosis, this book primarily will be of interest to residents and fellows in radiology, as well as radiologists. In spite of the cursory coverage of MR physics, medical physicists and medical physics residents also may find the clinical cases interesting and educational.
Features: "This book consists of four chapters, and includes more than 300 clinical MR images of very good quality. The first chapter on MR physics briefly introduces basic MR imaging principles, image encoding, contrast weighting, and MR safety. The author references YouTube videos that demonstrate fundamental MR principles, such as resonance, precession, and magnetic induction. His descriptions of MR imaging processes, such as phase encoding, are clever and easy to understand. Chapter 2 on artifacts presents 27 cases, each with one or more clinical MR images with artifacts, and poses three or four possible interpretations. For each case discussion, the author explains the image acquisition technique, the cause and appearance of the artifact, and strategies for minimizing or eliminating it. Finally, he provides the correct interpretation. The third chapter, on pitfalls, continues in the same case study format, presenting 24 head and spine cases. The author challenges readers to choose the correct diagnosis using the images provided and focuses the discussion on potential pitfalls. Additional images support the correct diagnosis or provide additional examples. The final chapter presents 10 cases to test readers' MR artifact-identification skills and their ability to arrive at the correct diagnosis, before providing a brief discussion and the correct diagnosis. A short list of suggested readings, primarily from radiology journals, ends each chapter. "
Assessment: The author succeeds in providing good clinical examples of MR artifacts with easy to understand explanations of the underlying MR principles. The book is enjoyable to read and the numerous clinical MR images are of very good quality. It is not a rigorous treatise on MR physics, nor is it intended to be. Radiologists, medical physicists, and trainees in those disciplines who would like to better understand the impact of MR artifacts on clinical image interpretation will benefit from this book.
From the Publisher
"Practical MR Physics strives to make the physics of MR understandable, categorize various MR artifacts and demonstrate pitfalls. Treatment is non-mathematical and is dealt with in a conversational and easy to understand manner. The sprinkling of historical notes in this section make for interesting reading. This book would be one to which residents and fellows in neuroradiology should have access...a valuable addition to a section's library."--American Journal of Neuroradiology
The book is enjoyable to read and the numerous clinical MR images are of very good quality...Radiologists, medical physicists, and trainees in those disciplines who would like to better understand the impact of MR artifacts on clinical image interpretation will benefit from this book." --Doody's
