The New Edition of this popular, practical resource offers a lucid introduction to the principles of MRI, explaining in plain language the general principles of magnetism and nuclear magnetic resonance induction, and how this phenomenon can be used to generate and manipulate images for clinical use. A wealth of high-quality illustrations, complemented by concise text, enable readers to gain a solid understanding without requiring in-depth knowledge of physics and mathematics. And, each lists of essential points at the end of each chapter enable readers to test and hone their knowledge.

Provides a clear understanding of the principles of MRI without assuming specialized knowledge of mathematics and physics.
Features a practical, clinical focus that reflects current practice standards.
Discusses how protocols change with each patient and procedure.
Offers comparative examples, showing an image at different MRI parameters.

Incorporates new techniques for functional and physiologic imaging.
Presents new techniques such as parallel functional imaging and a new method for filling k-space.
Offers fresh perspectives from physicist and expert in neuroimaging, Mark Cohen, PhD.
