MAGNETIC RESONANCE IMAGING
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.
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.

Functional Magnetic Resonance Imaging provides a comprehensive introduction to fMRI. The Third Edition has been extensively updated, including a discussion of the physiological basis of fMRI and coverage of ethical and methodological controversies. Example are drawn from both seminal historical work and cutting-edge current research.
The opening chapter of The Essential Guide to Magnetic Resonance presents applications of Fluorine-19 Magnetic Resonance Imaging (19F MRI) in cancer research, tissue metabolomics, quantification of drug delivery, cellular tracking, tissue pH measurements and detection of 19F labeled cells. The authors review in vitro research applying 19F MRI and Magnetic Resonance Spectroscopy (MRS) to facilitate the synthesis, tracking and visualization of new fluorinated drug conjugates. 19F MRI also provides high contrast in vivo images due to the absence of an endogenous 19F signal, 100% natural abundance of 19F, and a chemical shift range of over 400 ppm. Afterwards, examples of current methods of magnetic resonance imaging (MRI) guided photodynamic therapy are presented. Recent development of MRI detectable nanoparticle constructs, magnetic resonance spectroscopy (MRS) sensors, gadolinium based photosensitizers and europium singlet oxygen probes are discussed. In addition, applications of Functional MRI using a blood oxygen dependent level (BOLD) MRI in monitoring photodynamic action are addressed, with the goal of informing researchers about the potential for using MRI guided photodynamic therapy and oxygen dosimetry. The applications of MRI within the sphere of pharmacy are analyzed; in particular, the use of MRI to track pharmaceuticals in vitro and in vivo noninvasively and monitoring their controlled-release. Functional MRI for noninvasive clinical brain imaging is explored as it is applied to studies of autism, schizophrenia, epilepsy Alzheimers disease, Parkinson's disease, traumatic brain injury and blood oxygenation-level dependent (BOLD) imaging of brain function. An overview of the scope of MRI as a diagnostic technique in neurology and in neurosurgery is also provided.

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.

At the heart of every medical imaging technology is a sophisticated mathematical model of the measurement process and an algorithm to reconstruct an image from the measured data. This book provides a firm foundation in the mathematical tools used to model the measurements and derive the reconstruction algorithms used in most imaging modalities in current use. In the process, it also covers many important analytic concepts, and techniques used in Fourier analysis, integral equations, sampling theory, and noise analysis. This text uses X-ray computed tomography as a "pedagogical machine" to illustrate important ideas and incorporates extensive discussions of background material making the more advanced mathematical topics accessible to readers with a less formal mathematical education. The mathematical concepts are illuminated with over 200 illustrations and numerous exercises. New to the second edition are a chapter on magnetic resonance imaging (MRI), a revised section on the relationship between the continuum and discrete Fourier transforms, a new section on Grangreat's formula, an improved description of the gridding method, and a new section on noise analysis in MRI.
Through numerous examples, the principles of the relationship between chemical structure and the NMR spectrum are developed in a logical, step-by-step fashion * Includes examples and exercises based on real NMR data including full 600 MHz one- and two-dimensional datasets of sugars, peptides, steroids and natural products * Includes detailed solutions and explanations in the text for the numerous examples and problems and also provides large, very detailed and annotated sets of NMR data for use in understanding the material * Describes both simple aspects of solution-state NMR of small molecules as well as more complex topics not usually covered in NMR books such as complex splitting patterns, weak long-range couplings, spreadsheet analysis of strong coupling patterns and resonance structure analysis for prediction of chemical shifts * Advanced topics include all of the common two-dimensional experiments (COSY, ROESY, NOESY, TOCSY, HSQC, HMBC) covered strictly from the point of view of data interpretation, along with tips for parameter settings
Drug-resistant epilepsy with negative MRI is frequently seen in patients considered for epilepsy surgery; however, clinical evaluation and surgical treatment is very complex and challenging. Advanced imaging techniques are needed to detect the location of the epileptogenic zone. In most cases, intracranial EEG recording is required to delineate the region of seizure onset - this carries some risks of major complications. Moreover, the borders between the recorded seizure onset and the location of important brain functions are often indistinct in MRI-negative epilepsy. Overall, the outcome of MRI-negative surgery is less favorable than that of MRI-positive surgery, but it can significantly improve with optimal management. Each chapter critically appraises the role and value of specific diagnostic and treatment techniques to address the challenges of MRI-negative epilepsy surgery. Authors critique evidence and share their expertise on the diagnostic options and surgical approaches that make epilepsy surgery possible and worthwhile in patients with this condition.
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.
