In vivo magnetic resonance imaging (MRI) has evolved into a versatile and critical, if not ‘gold standard’, imaging tool with applications ranging from the physical sciences to the clinical ‘-ology’. In addition, there is a vast amount of accumulated but unpublished inside knowledge on what is needed to perform a safe, in vivo MRI. The goal of this comprehensive text, written by an outstanding group of world experts, is to present information about the effect of the MRI environment on the human body, and tools and methods to quantify such effects. By presenting such information all in one place, the expectation is that this book will help everyone interested in the Safety and Biological Effects in MRI find relevant information relatively quickly and know where we stand as a community. The information is expected to improve patient safety in the MR scanners of today, and facilitate developing faster, more powerful, yet safer MR scanners of tomorrow. This book is arranged in three sections. The first, named ‘Static and Gradient Fields’ (Chapters 1-9), presents the effects of static magnetic field and the gradients of magnetic field, in time and space, on the human body. The second section, named ‘Radiofrequency Fields’ (Chapters 10-30), presents ways to quantify radiofrequency (RF) field induced heating in patients undergoing MRI. The effect of the three fields of MRI environment (i.e. Static Magnetic Field, Time-varying Gradient Magnetic Field, and RF Field) on medical devices, that may be carried into the environment with patients, is also included. Finally, the third section, named ‘Engineering’ (chapters 31-35), presents the basic background engineering information regarding the equipment (i.e. superconducting magnets, gradient coils, and RF coils) that produce the Static Magnetic Field, Time-varying Gradient Magnetic Field, and RF Field. The book is intended for undergraduate and post-graduate students, engineers, physicists, biologists, clinicians, MR technologists, other healthcare professionals, and everyone else who might be interested in looking into the role of MRI environment on patient safety, as well as those just wishing to update their knowledge of the state of MRI safety. Those, who are learning about MRI or training in magnetic resonance in medicine, will find the book a useful compendium of the current state of the art of the field.

The book summarizes the emerging topic about the effects of SMF on biological samples ranging from single molecules, subcellular compartments, and cells to whole organisms. It also discusses the potential application of SMF in clinical treatment of cancer, pain, diabetes and other diseases. With the development and growing popularity of modern appliances like MRI in hospitals, the potential impact of magnetic fields on human health is invoking increasing concerns. At the same time, SMF has been explored in the treatment of tumor and other diseases for decades. Nevertheless, there are still some reservations and uncertainties about these treatments, which are largely due to the differential biological effects reported in the literature. These experimental inconsistencies are mainly caused by variations such as different magnetic field types, intensities, treatment time, as well as biological samples examined. The second edition added eight new chapters about new progress in this field including impacts of SMFs, magnetism of biomolecules, and potential of SMFs in the management of bone, pain, diabetes, and immune systems. This volume will help clarify some dilemmas in this field and encourage further investigations in order to achieve a better understanding of the biological effects of SMF, aiming for a rational application of SMF in clinical therapy in the near future. The book is useful for scientists, doctors, and students who are interested in magnetic fields and life sciences

Study of the biological effect of magnetic fields is both a very old and a very recent area of investigation. A connection between health and the mysterious force of the lodestone has been suspected since the dawn of human culture. Nevertheless, only during the last decades has reliable evidence of biological effects of the magnetic field been dis covered. The purpose of this book is to bring together in one volume the present-day knowledge in all the active fields of biomagnetic research and at the same time to provide a theoretical and practical background to all scientists who wish to engage in investigations in this new disci pline. The need for such a comprehensive survey of current informa tion became evident to the editor from the interest manifested in the biomagnetic symposia and from the extended correspondence maintained by the Biomagnetic Research Foundation. It is hoped that the book will aid in attracting the interest of specialists and may thus serve as a catalyst for interdisciplinary exchange of ideas.

We define biomagnetism broadly as the science of processes and functions in living organisms induced by static magnetic fields. Biomagnetic research has greatly increased since the publication of the first volume of this series. While much of this work has been reported in various international journals, there exists a need for this work to be collected together in one place. This book covers a rather wide area of research, both with respect to the strength of the field, ranging from "zero" to 150,000 oersteds, and with respect to the various specimens and their biological functions. It is designed primarly to help clarify the action of magnetic fields on biological systems with the hope of achieving a better understanding of the fundamental physiological processes occurring in them. In some chapters it is suggested that magnetic fields could ultimately be used in the treatment of disease. I would like to take this occasion to thank the contributors for their generous interest and willing cooperation. M. F. B. June 1969 Chicago, Illinois v CONTRIBUTORS Robert A.

This volume presents the proceedings of a New York Academy of Sciences conference, held in May 1991. It represents an up-to-date assessment of the biological effects and safety hazards associated with magnetic resonance imaging (MRI) and spectroscopy. The interaction of electric and magnetic fields present within the surrounding MRI systems with cells, organs and whole animals is carefully analysed. Experts in medicine, medical physics and bioelectromagnetics provide a review of the hazards known to occur in existing MRI systems and a framework for the study of new problems that may emerge with the development of advanced MRI systems.

MR is a powerful modality. At its most advanced, it can be used not just to image anatomy and pathology, but to investigate organ function, to probe in vivo chemistry, and even to visualise the brain thinking. However, clinicians, technologists and scientists struggle with the study of the subject. The result is sometimes an obscurity of understanding, or a dilution of scientific truth, resulting in misconceptions. This is why MRI from Picture to Proton has achieved its reputation for practical clarity. MR is introduced as a tool, with coverage starting from the images, equipment and scanning protocols and traced back towards the underlying physics theory. With new content on quantitative MRI, MR safety, multi-band excitation, Dixon imaging, MR elastography and advanced pulse sequences, and with additional supportive materials available on the book's website, this new edition is completely revised and updated to reflect the best use of modern MR technology.
