This book is for all those professionals directly or indirectly working in magnetic resonance, and arises from the need to have available a complete and comprehensible guide, in order to recognize, construe and work out almost all the artifacts that can currently be observed in the supplied scanners, being low-field, mid-field, high-field or ultra-high-field. The content includes many demonstrative images and few mathematical formula, moreover simple to be construed, in order to make easily comprehensible the complex mechanisms hidden behind MR Physics, connected to the artifact under consideration. The text presents a basic introduction to the magnetic resonance and a glossary of used acronyms, so that the principles related to k-space, impulse sequences and relaxation times are clearly understood. Artifacts are effectively classified in chapters and subchapters, according to the underlying cause generating them. Each artifacts group is dealt with following a logic providing for: -Introduction to the specific artifact-related technique.-Modes by which the artifact shows itself, on the basis of images and text.-Technical solutions suited to the resolutions.-Online examinations, videos, focuses, overview tables with access linked to the credentials obtained when purchasing the original text. The online section is available only for the paperback edition
