Genre: Mathematics

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 funktioniert eigentlich MRI? Diese Frage wird so oft gestellt, daß wir uns entschlossen haben, unser Modell von der Funktionsweise dieser faszinierenden und zukunftsweisenden Methode zusammen zufassen. Modell, notabene, denn in Tat und Wahrheit sind die physikali schen und technischen Hintergründe viel komplizierter, als wir sie hier darstellen. Aber dieses Skript richtet sich auch nicht an Physiker innen und Physiker, sondern an all diejenigen, die sich für MRI inter essieren, regelmäßig damit zu tun haben oder einfach sonst genauer wissen möchten, was hinter MRI steckt, also z. B. an Ärztinnen und Ärzte, MTRAs, Studentinnen und Studenten. Das Ziel ist deshalb nicht eine fundierte und exakte Abhandlung aller physikalischen Zusam menhänge und Formeln, sondern eine (hoffentlich) verständliche Einführung in die Prinzipien der MR-Bildgebung. Insbesondere werden (hoffentlich!) alle wichtigen Begriffe behan delt, die auch in der klinischen Anwendung von Bedeutung sind, und es wird versucht, die zugrundeliegenden physikalischen Vorgänge verständlich zu machen. Es geht also trotz allem nicht ohne ein bi߭ chen Physik! Wir danken allen, die uns bei der Verbesserung dieses Skripts mit Rat und Kritik geholfen haben. Besonderer Dank gebührt an dieser Stelle Herrn Constantin von Weymarn, der bei der Überarbeitung des Skripts geholfen und die physikalischen Grundlagen abgesichert hat. Außerdem danken wir Herrn Johannes Fröhlich von der Firma Guerbet AG für seine zahlreichen konstruktiven Anregungen. Wir sind auch in Zukunft froh um jede Kritik, die es uns ermöglicht, diese Ein führung zu verbessern, damit sie ihr Ziel erreichen kann.

Ultra Low Field Nuclear Magnetic Resonance

Author: Robert Kraus Jr.
Publisher: Oxford University Press
ISBN: 9780199347889
Release Date: 2014-02-26
Genre: Medical

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.

Imaging in Neurodegenerative Disorders

Author: Luca Saba
Publisher: OUP Oxford
ISBN: 9780191651403
Release Date: 2015-01-08
Genre: Medical

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.
