Magnetic Resonance Imaging (MRI) is among the most important medical imaging techniques available today. There is an installed base of approximately 15,000 MRI scanners worldwide. Each of these scanners is capable of running many different "pulse sequences", which are governed by physics and engineering principles, and implemented by software programs that control the MRI hardware. To utilize an MRI scanner to the fullest extent, a conceptual understanding of its pulse sequences is crucial. Handbook of MRI Pulse Sequences offers a complete guide that can help the scientists, engineers, clinicians, and technologists in the field of MRI understand and better employ their scanner. Explains pulse sequences, their components, and the associated image reconstruction methods commonly used in MRI Provides self-contained sections for individual techniques Can be used as a quick reference guide or as a resource for deeper study Includes both non-mathematical and mathematical descriptions Contains numerous figures, tables, references, and worked example problems
Wie schon die beiden vorherigen Auflagen, führt dieses Buch kurz und prägnant in die Physik und Funktionsweise der Magnetresonanztomographie ein. Insbesondere werden alle wichtigen Begriffe, die in der Klinik von Bedeutung sind und die zugrundeliegenden physikalischen Vorgänge verständlich gemacht. Entsprechend liegt der Schwerpunkt auf einem klar strukturierten Aufbau. Alle Kapitel wurden überarbeitet und auf den neuesten Stand des Wissens gebracht. Neu sind die Kapitel "Determinanten des Signal-zu-Rausch-Verhältnisses" und "Sicherheit und Risiken". Der zunehmenden Bedeutung des MRI in der nichtinvasiven Gefässdiagnostik wird mit einem speziellen Kapitel Rechnung getragen. Die Kapitel über MR-Sequenzen wurden neu gegliedert, um der Entwicklung zu immer schnelleren Sequenzen gerecht zu werden. Das Buch richtet sich in erster Linie an Ärzte, MTRAs und Studenten, die sich mit den Grundlagen der MR-Bildgebung vertraut machen wollen.

This book is designed to introduce the reader to the field of NMR/MRI at very low magnetic fields, from milli-Tesla to micro-Tesla, the ultra-low field (ULF) regime. The book is focused on applications to imaging the human brain, and hardware methods primarily based upon pre-polarization methods and SQUID-based detection. The goal of the text is to provide insight and tools for the reader to better understand what applications are best served by ULF NMR/MRI approaches. A discussion of the hardware challenges, such as shielding, operation of SQUID sensors in a dynamic field environment, and pulsed magnetic field generation are presented. One goal of the text is to provide the reader a framework of understanding the approaches to estimation and mitigation of low signal-to-noise and long imaging time, which are the main challenges. Special attention is paid to the combination of MEG and ULF MRI, and the benefits and challenges presented by trying to accomplish both with the same hardware. The book discusses the origin of unique relaxation contrast at ULF, and special considerations for image artifacts and how to correct them (i.e. concomitant gradients, ghost artifacts). A general discussion of MRI, with special consideration to the challenges of imaging at ULF and unique opportunities in pulse sequences, is presented. The book also presents an overview of some of the primary applications of ULF NMR/MRI being pursued.

Diagnosing neurodegenerative diseases can prove particularly intimidating to clinicians, because many times the diagnosis cannot be critically "confirmed" by a simple test. New imaging modalities have advanced to the point of high resolution, morphological, metabolic and functional analysis. Computed tomography, magnetic resonance, nuclear medicine and molecular imaging have recently emerged as outstanding non-invasive techniques for the study of the neurodegenerative disorders. Imaging in Neurodegenerative Disorders covers all the imaging techniques and new exciting methods like new tracers, biomarker, metabolomic and gene-array profiling, potential for applying such techniques clinically, and offers present and future applications as applied to the neurodegenerative disorders with the most world renowned scientists in these fields. This book is an invaluable resource for researchers, clinicians, and trainees in neuroscience, neurology, psychiatry, and radiology.

MRI: Essentials for Innovative Technologies describes novel methods to improve magnetic resonance imaging (MRI) beyond its current limitations. It proposes smart encoding methods and acquisition sequences to deal with frequency displacement due to residual static magnetic field inhomogeneity, motion, and undersampling. Requiring few or no hardware modifications, these speculative methods offer building blocks that can be combined and refined to overcome barriers to more advanced MRI applications, such as real-time imaging and open systems. After a concise review of basic mathematical tools and the physics of MRI, the book describes the severe artifacts produced by conventional MRI techniques. It first tackles magnetic field inhomogeneities, outlining conventional solutions as well as a completely different approach based on time-varying gradients and temporal frequency variation coding (acceleration). The book then proposes two innovative acquisition methods for reducing acquisition time, motion, and undersampling artifacts: adaptive acquisition and compressed sensing. The concluding chapter lays out the author’s predictions for the future of MRI. For some of the proposed solutions, this is the first time the reported results have been published. Where experimental data is preliminary or unavailable, the book presents only numerical solutions. Offering insight into emerging MRI techniques, this book provides readers with specialized knowledge to help them design better acquisition sequences and select appropriate correction methods. The author’s proceeds from the sale of this book will be entirely donated to Bambin Gesù Children’s Hospital in Rome.
