In Vivo EPR (ESR) is a textbook on this relatively new subject in biomedical electron spin resonance. While a few chapters have appeared in special topics volumes in this series, this book covers the principles and theory, instrumentation as well as the latest applications at the time of its writing. The authors are world-renowned experts and pioneers in their fields. This book is divided into two major sections dealing with theory and instrumentation, and aspects of biochemistry, in vitro and in vivo applications. A significant amount of detail is devoted to clinical applications and the problems and pitfalls encountered in in vivo spectroscopy and imaging. Key Features: -History of In Vivo EPR, -Principles of Imaging-Theory and Instrumentation, -Time-domain Radio Frequency EPR Imaging, -The Measurement of Oxygen In Vivo Using In Vivo EPR Techniques, -Potential Medical (Clinical) Applications of EPR, -Combining NMR and EPR/ESR for In Vivo Experiments.
