This textbook focuses on developing an understanding of the fundamental physical processes that take place inside the body that can be probed by magnetic resonance imaging (MRI) and magnetic resonance spectroscopy (MRS). The material presented in this book bridges the gap between the physics of magnetic resonance (MR) image formation and the in vivo processes that influence the detected signals, equipping the reader with the required tools that are essential to study the spin interactions leading to various contrast mechanisms.

Daniel M. Spielman, PhD, is Professor of Radiology at Stanford University, Stanford, CA, USA. He is a fellow of both the American Institute for Medical & Biological Engineering (AIMBE) and International Society of Magnetic Resonance in Medicine (ISMRM), and has received multiple teaching awards including the ISMRM Outstanding Teacher Award (2005) and Stanford Department of Radiology Research Faculty of the Year (2022).

Keshav Datta, PhD, is Vice President, Research & Development, at VIDA Diagnostics Inc., Coralville, IA, USA, a precision lung health company, accelerating therapies to patients through AI-powered lung intelligence.. He is also a Consulting Research Scientist at Stanford University, Stanford, CA, USA.
