Nuclear magnetic resonance (NMR) is a physical phenomenon in which nuclei in a magnetic field absorb and re-emit electromagnetic radiation. This energy is at a specific resonance frequency which depends on the strength of the magnetic field and the magnetic properties of the isotope of the atoms. NMR allows the observation of specific quantum mechanical magnetic properties of the atomic nucleus. Many scientific techniques exploit NMR phenomena to study molecular physics, crystals, and non-crystalline materials through nuclear magnetic resonance spectroscopy. NMR is also routinely used in advanced medical imaging techniques, such as in magnetic resonance imaging (MRI), by which biochemical information can be obtained from living tissue (e.g. human brain tumors) with the technique known as in vivo magnetic resonance spectroscopy or chemical shift NMR Microscopy.

In the present book, fifteen typical literatures about NMR in biomedical field published on international authoritative journals were selected to introduce the worldwide newest progress, which contains reviews or original researches on scientific techniques, medical science, biomedical applications, ect. We hope this book can demonstrate advances in NMR in biomedical field as well as give references to the researchers, students and other related people.
