Book Synopsis Physics of Clinical MR Taught Through Images by : Val M. Runge

Download or read book Physics of Clinical MR Taught Through Images written by Val M. Runge. This book was released on 2011-01-01. Available in PDF, EPUB and Kindle. Book excerpt: Award Winner, RSNA 2009! This lavishly illustrated book uses high-quality images to present a practical guide to the physics of magnetic resonance. Written by internationally renowned authors, the book places an emphasis on learning visually through images of real cases rather than through mathematical equations and provides the fundamental information needed to achieve the best images in everyday clinical practice. This edition features new images and incorporates information on the latest technical advances in the field, discussing such important topics as 3 T, specific absorption rate (SAR), arterial spin labeling, continuous moving table MR, and time-resolved contrast enhanced MR angiography.Highlights: Concise chapters make difficult concepts easy to digest 400 high-quality images and illustrations demonstrate key concepts This book is a valuable reference for radiologists and an excellent resource for residents preparing for board examinations. It is also ideal for MR technologists and students seeking to fully understand the basic principles underlying this important diagnostic tool.

Book Synopsis The Physics of Clinical MR Taught Through Images by : Val M. Runge

Download or read book The Physics of Clinical MR Taught Through Images written by Val M. Runge. This book was released on 2018-05-07. Available in PDF, EPUB and Kindle. Book excerpt: The fourth edition of The Physics of Clinical MR Taught Through Images The Physics of Clinical MR Taught Through Images Fourth Edition by Val Runge, Wolfgang Nitz, and Johannes Heverhagen presents a unique and highly practical approach to understanding the physics of magnetic resonance imaging. Each physics topic is described in user-friendly language and accompanied by high-quality graphics and/or images. The visually rich format provides a readily accessible tool for learning, leveraging, and mastering the powerful diagnostic capabilities of MRI. Key Features More than 700 images, anatomical drawings, clinical tables, charts, and diagrams, including magnetization curves and pulse sequencing, facilitate acquisition of highly technical content. Eight systematically organized sections cover core topics: hardware and radiologic safety; basic image physics; basic and advanced image acquisition; flow effects; techniques specific to the brain, heart, liver, breast, and cartilage; management and reduction of artifacts; and improvements in MRI diagnostics and technologies. Cutting-edge topics including contrast-enhanced MR angiography, spectroscopy, perfusion, and advanced parallel imaging/data sparsity techniques. Discussion of groundbreaking hardware and software innovations, such as MR-PET, 7 T, interventional MR, 4D flow, CAIPIRINHA, radial acquisition, simultaneous multislice, and compressed sensing. A handy appendix provides a quick reference of acronyms, which often differ from company to company. The breadth of coverage, rich visuals, and succinct text make this manual the perfect reference for radiology residents, practicing radiologists, researchers in MR, and technologists.
