Book excerpt: Students of radiology and radiography at both undergraduate andpostgraduate level often experience difficulty in learning MRItechniques. This book provides concise, easily accessibleinformation on MRI physics which can be used as a revision tool. Topics covered include relaxation processes, image contrast,pulse sequences, image production, image quality, artefacts, MRA,instrumentation and safety. Double page spreads for each sectionwill contain a diagram and/or image depicting the main concepts ofMR physics together with a succinct account of the topic in bulletpoints and tables.
