In the past few decades, Magnetic Resonance Imaging (MRI) has become an indispensable tool in modern medicine, with MRI systems now available at every major hospital in the developed world. But for all its utility and prevalence, it is much less commonly understood and less readily explained than other common medical imaging techniques. Unlike optical, ultrasonic, X-ray (including CT), and nuclear medicine-based imaging, MRI does not rely primarily on simple transmission and/or reflection of energy, and the highest achievable resolution in MRI is orders of magnitude smaller that the smallest wavelength involved. In this book, MRI will be explained with emphasis on the magnetic fields required, their generation, their concomitant electric fields, the various interactions of all these fields with the subject being imaged, and the implications of these interactions to image quality and patient safety. Classical electromagnetics will be used to describe aspects from the fundamental phenomenon of nuclear precession through signal detection and MRI safety. Simple explanations and Illustrations combined with pertinent equations are designed to help the reader rapidly gain a fundamental understanding and an appreciation of this technology as it is used today, as well as ongoing advances that will increase its value in the future. Numerous references are included to facilitate further study with an emphasis on areas most directly related to electromagnetics.

The author of this book has been contributing to developments of an electron paramagnetic resonance (EPR) imaging system and its applications for more than 10 years. This system was designed for EPR measurements of experimental animals such as rats and mice, and its applications were mainly for biological researches. Thus, a lot of parameters to design an EPR imaging system are determined on the assumption that this system can be used for in vivo studies. The main aim of performing in vivo EPR measurements is to estimate in vivo reducing ability that cannot be obtained by other measuring methods at present. In this book, before main chapters about EPR imaging, this aim and specifications of apparatuses for achieving this aim are stated as a background. After description of instrumental components of an in vivo spectrometer, a theory, instruments, data processing, and applications of EPR imaging are explained. In the chapters about instruments and data processing, their details are described so that one can build the apparatus and obtain data. In the chapter about applications, examples of in vivo estimation of reducing ability in experimental models of some diseases are presented. In the last chapter, an explanation about region-selected intensity determination (RSID), a novel method that allows estimation of in vivo reducing ability at a selected anatomical region without complications of previous EPR imaging method, is stated.

Magnetic Resonance Imaging, not so long ago a diagnostic tool of last resort, has become pervasive in the landscape of consumer medicine; images of the forbidding tubes, with their promises of revelation, surround us in commercials and on billboards. Magnetic Appeal offers an in-depth exploration of the science and culture of MRI, examining its development and emergence as an imaging technology, its popular appeal and acceptance, and its current use in health care. Understood as modern and uncontroversial by health care professionals and in public discourse, the importance of MRI or its supposed infallibility has rarely been questioned. In Magnetic Appeal, Kelly A. Joyce shows how MRI technology grew out of serendipitous circumstances and was adopted for reasons having little to do with patient safety or evidence of efficacy. Drawing on interviews with physicians and MRI technologists, as well as ethnographic research conducted at imaging sites and radiology conferences, Joyce demonstrates that current beliefs about MRI draw on cultural ideas about sight and technology and are reinforced by health care policies and insurance reimbursement practices. Moreover, her unsettling analysis of physicians' and technologists' work practices lets readers consider that MRI scans do not reveal the truth about the body as is popularly believed, nor do they always lead to better outcomes for patients. Although clearly a valuable medical technique, MRI technology cannot necessarily deliver the health outcomes ascribed to it. Magnetic Appeal also addresses broader questions about the importance of medical imaging technologies in American culture and medicine. These technologies, which include ultrasound, X-ray, and MRI, are part of a larger trend in which visual representations have become central to American health, identity, and social relations."
Magnetic resonance systems are used in almost every academic and industrial chemistry, physics and biochemistry department, as well as being one of the most important imaging modalities in clinical radiology. The design of such systems has become increasingly sophisticated over the years. Static magnetic fields increase continuously, large-scale arrays of receive elements are now ubiquitous in clinical MRI, cryogenic technology has become commonplace in high resolution NMR and is expanding rapidly in preclinical MRI, specialized high strength magnetic field gradients have been designed for studying the human connectome, and the commercial advent of ultra-high field human imaging has required new types of RF coils and static shim coils together with extensive electromagnetic simulations to ensure patient safety. This book covers the hardware and engineering that constitutes a magnetic resonance system, whether that be a high-resolution liquid or solid state system for NMR spectroscopy, a preclinical system for imaging animals or a clinical system used for human imaging. Written by a team of experts in the field, this book provides a comprehensive and instructional look at all aspects of current magnetic resonance technology, as well as outlooks for future developments.

Magnetic resonance imaging (MRI) is a technique used in biomedical imaging and radiology to visualize internal structures of the body. Because MRI provides excellent contrast between different soft tissues, the technique is especially useful for diagnostic imaging of the brain, muscles, and heart. In the past 20 years, MRI technology has improved significantly with the introduction of systems up to 7 Tesla (7 T) and with the development of numerous post-processing algorithms such as diffusion tensor imaging (DTI), functional MRI (fMRI), and spectroscopic imaging. From these developments, the diagnostic potentialities of MRI have improved impressively with an exceptional spatial resolution and the possibility of analyzing the morphology and function of several kinds of pathology. Given these exciting developments, the Magnetic Resonance Imaging Handbook: Image Principles, Neck, and the Brain is a timely addition to the growing body of literature in the field. Covering MRI from fundamentals to practice, this comprehensive book: Discusses the clinical benefits of diagnosing human pathologies using MRI Explains the physical principles of MRI and how to use the technique correctly Highlights each organ's anatomy and pathological processes with high-quality images Examines the protocols and potentialities of advanced MRI scanners such as 7 T systems Includes extensive references at the end of each chapter to enhance further study Thus, the Magnetic Resonance Imaging Handbook: Image Principles, Neck, and the Brain provides radiologists and imaging specialists with a valuable, state-of-the-art reference on MRI.
Arterial Spin Labeling (ASL) is an increasingly popular tool to study the brain. What sets it apart from other neuroimaging methods is the combination of quantitative measurements of a physiologically well-defined process, namely perfusion, and a completely non-invasive acquisition methodology. Cerebral perfusion is a critical component to brain health, as it is the primary means to deliver nutrients to support brain function as well as clearing waste products. Hence it is a useful quantity to study in disease where changes in perfusion can indicate regions of the brain that are pathological. Likewise changes in perfusion can be indicative of greater demand for nutrients, such as might be required in response to an increase in neuronal activity. With the advent of a consensus by the ASL community on good practice and a recommendation on robust methods for ASL data collection, more and more researchers are now able to access and use ASL. Despite the technological advances, ASL remains a technique with a low signal to noise ratio. This makes the wise choice of the appropriate analysis methods more important. The aim of this primer is to equip someone new to the field of perfusion imaging and ASL with the knowledge not only to make good choices about ASL acquisition and analysis, but also to understand what choices they are making and why. Examples of analysis applied to real data are given throughout the text and instructions on how to reproduce the analyses are illustrated on the primer website. Written to provide a stand-alone introduction to perfusion qualification using ASL, this primer also works with other texts in the Oxford Neuroimaging Primers series to provide a comprehensive overview of the increasingly influential field of neuroimaging.
Over the past decade, fluorine (19F) magnetic resonance imaging (MRI) has garnered significant scientific interest in the biomedical research community owing to the unique properties of fluorinated materials and the 19F nucleus. Fluorine has an intrinsically sensitive nucleus for MRI. There is negligible endogenous 19F in the body and thus there is no background signal. Fluorine-containing compounds are ideal tracer labels for a wide variety of MRI applications. Moreover, the chemical shift and nuclear relaxation rate can be made responsive to physiology via creative molecular design. This book is an interdisciplinary compendium that details cutting-edge science and medical research in the emerging field of 19F MRI. Edited by Ulrich Floegel and Eric Ahrens, two prominent MRI researchers, this book will appeal to investigators involved in MRI, biomedicine, immunology, pharmacology, probe chemistry, and imaging physics.

In this autobiography, Sir Peter Mansfield describes his life from war time childhood that initially sparked his interest in physics to his work in magnetic resonance imaging (MRI) that eventually led to the award of the Nobel Prize in 2003. Peter Mansfield grew up in London, but was evacuated to Devon during the blitz and following the V1 and V2 attacks on London. At the end of hostilities, he worked briefly in the printing industry before deciding to pursue his real interests in science by joining the Rocket Propulsion Department at Westcott near Aylesbury. Following a period of National Service and his studies at Queen Mary College, University of London, he married and moved to the USA for two years, returning in 1964 as a Lecturer in Physics at the University of Nottingham. In 1972 he spent a sabbatical period in Heidelberg, and during this period corresponded with his student, Peter Grannell, in Nottingham on the novel idea of magnetic resonance imaging. This led to his first paper on MRI which was presented at the first Specialised Colloque Ampere in 1973. During this period, he demonstrated how the MRI radio signals can be analysed and turned into images of the body. In 2003 the Nobel Prize in Physiology or Medicine was awarded jointly to Sir Peter and Paul Lauterbur for their crucial achievements in the development of MRI.

This is the first textbook dedicated to CEST imaging and covers the fundamental principles of saturation transfer, key features of CEST agents that enable the production of imaging contrast, and practical aspects of preparing image-acquisition and post-processing schemes suited for in vivo applications. CEST is a powerful MRI contrast mechanism with unique features, and the rapid expansion it has seen over the past 15 years since its original discovery in 2000 has created a need for a graduate-level handbook describing all aspects of pre-clinical, translational, and clinical CEST imaging. The book provides an illustrated historical perspective by leaders at the five key sites who developed CEST imaging, from the initial saturation transfer NMR experiments performed in the 1960s in Stockholm, Sweden, described by Sture Forsen, to the work on integrating the basic principles of CEST into imaging by Robert Balaban, Dean Sherry, Silvio Aime, and Peter van Zijl in the United States and Italy. The editors, Drs. Michael T. McMahon, Assaf A. Gilad, Jeff W. M. Bulte, and Peter C. M. van Zijl, have been pioneers developing this field at the Johns Hopkins University School of Medicine and the Kennedy Krieger Institute including contributions to Nature Medicine, Nature Biotechnology, Nature Materials, and the Proceedings of the National Academy of Sciences. As recognition for their initial development of the field, Drs. van Zijl and Balaban were awarded the Laukien Prize in April 2016, established in 1999 to honor the memory of Professor Gunther Laukien, a co-founder of Bruker Biospin GmbH.
