Now in its updated Second Edition, this volume is an easy-to-read introduction to the physics behind MR imaging. The subject is presented in a clear, user-friendly, clinically relevant fashion, with large-size, legible equations, over 100 images of cases to illustrate the basic principles described in the text, and questions and answers that are ideal for board review. This edition has new images and up-to-date information on echo planar imaging, contrast enhanced MR angiography, diffusion tensor imaging, and using high-performance gradients. A new chapter provides a clinical approach to pulse sequences, to help readers assess the utility of newer sequences. The review section has additional questions.
