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 In addition, there is a vast amount of accumulated but unpublished inside knowledge on what is needed to perform a safe, in vivo MRI.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.

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.

Magnetic resonance imaging (MRI) is relatively safe imaging modality that does not involve ionizing radiation and is used for diagnostic purpose; it involves both static and time varying magnetic fields, beside RF electromagnetic waves. MR imaging applied to living tissues provides a promising new technique for medical imaging but there were no clear demonstration of MRI biological effects. This book review number of scientific researches and studies on that points and also it presents an experimental work that assess the hematological and histological effects of the electromagnetic radiation used in the MRI as repeated exposure effects on different blood parameters .This book also pressed on the safety considerations in MR imaging when the examinations were applied. So this book provides knowledge about the biological effects for Diagnostic Radiologists and Technologists.
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.
Essentials of MRI Safety is a comprehensive guide that enables practitioners to recognise and assess safety risks and follow appropriate and effective safety procedures in clinical practice. The text covers all the vital aspects of clinical MRI safety, including the bio-effects of MRI, magnet safety, occupational exposure, scanning passive and active implants, MRI suite design, institutional governance, and more. Complex equations and models are stripped back to present the foundations of theory and physics necessary to understand each topic, from the basic laws of magnetism to fringe field spatial gradient maps of common MRI scanners. Written by an internationally recognised MRI author, educator, and MRI safety expert, this important textbook: Reflects the most current research, guidelines, and MRI safety information Explains procedures for scanning pregnant women, managing MRI noise exposure, and handling emergency situations Prepares candidates for the American Board of MR Safety exam and other professional certifications Aligns with MRI safety roles such as MR Medical Director (MRMD), MR Safety Officer (MRSO) and MR Safety Expert (MRSE) Contains numerous illustrations, figures, self-assessment tests, key references, and extensive appendices Essentials of MRI Safety is an indispensable text for all radiographers and radiologists, as well as physicists, engineers, and researchers with an interest in MRI.
Magnetic Resonance Procedures: Health Effects and Safety is the first authoritative text on MR procedures and its associated health and safety concerns written by noted radiologists, physicists, and scientists with expertise in the field. It contains both theoretical and practical information. This timely text discusses emergent issues related to MR imaging and concerns such as shielding, the safe use of contrast agents, and management of patients with claustrophobia, anxiety, and emotional stress. It also contains a sample pre-MR screening form; comprehensive safety information for over 700 implants, devices, and materials; a list of medical devices and products for interventional MR procedures; and a summary of peer-reviewed MR safety studies. In the wake of recent government demands for increased patient safety in hospitals, along with the rapidly expanding use of MRI, this book is particularly important. It is the definitive resource for information on the safety aspects of magnetic resonance procedures.
