In the past few decades, Magnetic Resonance Imaging (MRI) has become an indispensable tool in modern medicine. But for all its utility and prevalence, it is much less commonly understood and less readily explained than other common medical imaging techniques.

In this book, MRI will be explained with emphasis on the magnetic fields required, their generation, their concomitant electric fields, the various interactions of all these fields with the subject being imaged, and the implications of these interactions to image quality and patient safety. Simple explanations and Illustrations combined with pertinent equations are designed to help the reader rapidly gain a fundamental understanding and an appreciation of this technology as it is used today, as well as ongoing advances that will increase its value in the future.
