Award Winner, RSNA 2009! This lavishly illustrated book uses high-quality images to present a practical guide to the physics of magnetic resonance. Written by internationally renowned authors, the book places an emphasis on learning visually through images of real cases rather than through mathematical equations and provides the fundamental information needed to achieve the best images in everyday clinical practice. This edition features new images and incorporates information on the latest technical advances in the field, discussing such important topics as 3 T, specific absorption rate (SAR), arterial spin labeling, continuous moving table MR, and time-resolved contrast enhanced MR angiography.Highlights: Concise chapters make difficult concepts easy to digest 400 high-quality images and illustrations demonstrate key concepts This book is a valuable reference for radiologists and an excellent resource for residents preparing for board examinations. It is also ideal for MR technologists and students seeking to fully understand the basic principles underlying this important diagnostic tool.

The objective of this 5th edition of the book, as with the prior editions, is to teach through images a practical approach to magnetic resonance (MR) physics and image quality. Unlike other texts covering this topic, the focus is on clinical images rather than equations. A practical approach to MR physics is developed through images, emphasizing knowledge of fundamentals important to achieve high image quality. Pulse diagrams are also included, which many at first find difficult to understand. Readers are encouraged to glance at these as they go through the text. With time and repetition, as a reader progresses through the book, the value of these and the knowledge thus available will become evident (and the diagrams themselves easier to understand). The text is organized into concise chapters, each discussing an important point relevant to clinical MR and illustrated largely with images from routine patient exams. The topics covered encompass the breadth of the field, from imaging basics and pulse sequences to advanced topics including contrast-enhanced MR angiography, spectroscopy, perfusion and advanced parallel imaging/data sparsity techniques. Discussion of the latest hardware and software innovations, for example next generation low field MR, deep learning, MR-PET, 7 T, interventional MR, 4D flow, CAIPIRINHA, spiral techniques, radial acquisition, simultaneous multislice, compressed sensing and MR fingerprinting, is included because these topics are critical to current clinical practice as well as to future advances. Included in the fifth edition are a large number of new topics, keeping the text up to date in this increasingly complex field. The text has also been thoroughly revised to include additional relevant clinical images, to improve the clarity of descriptions, and to increase the depth of content. The book is highly recommended for radiologists, physicists, and technologists interested in the background of image acquisition used in standard as well as specialized clinical settings.

Designed specifically for orthopedic surgeons involved in the review of musculoskeletal MRIs, this book enables clinicians to develop a systematic approach to the interpretation of MRI studies. It opens by providing clinicians with a solid understanding of essential concepts, including the physics of MRI, various pulse sequences available for obtaining an MRI, and normal MRI anatomy. The authors then present an overview of core concepts of image interpretation and step-by-step guidance on how to determine which pulse sequences have been utilized, how to evaluate images, and how to correlate imaging findings with patient history and clinical presentation. The remaining sections of the book present protocols for acquiring and interpreting MRIs of the upper extremity, lower extremity, and spine. Additional chapters cover special considerations for imaging articular cartilage and soft-tissue and bone tumors, as well as advanced techniques such as MR arthrography and MR angiography, correlation with other imaging modalities, and safety issues.Features: More than 700 MRIs and instructive illustrations to highlight key concepts related to normal anatomy and pathologic processes Practical discussion of how other imaging modalities correlate with MRI Clinical insights from leading orthopedic surgeons and radiologists An ideal resource for orthopedic surgeons, residents, and fellows, this book provides essential instruction on how to approach MRI studies in everyday practice. With its practical coverage of clinical concepts, this book will also serve as a valuable reference for radiologists, rheumatologists, primary care physicians, and other specialists who care for patients with musculoskeletal conditions.
