High-resolution nuclear magnetic resonance (NMR) spectroscopy and the magnetic resonance imaging (MRI) scanner seem to be worlds apart, but the underlying physical principles are the same, and it makes sense to treat them together. Chemists and clinicians who use magnetic resonance have much to learn about each other's specialties if they are to make the best use of magnetic resonance technology. Many in the medical fraternity will benefit from a general appreciation of how high-resolution NMR has advanced understanding of human biochemistry, diagnostic medicine, and the search for new drugs. This book also should prove of interest to doctors who make use of the MRI scanner. At the other end of the spectrum, chemists and biochemists that use high-resolution NMR spectroscopy will benefit from the exciting new developments in MR imaging and in vivo spectroscopy, as one justification for their research is the eventual benefit to health care. Finally, anyone interested in cognitive neuroscience will find a chapter devoted to the exciting new developments in functional magnetic resonance imaging of the brain. The treatment in this book is pictorial rather than mathematical.
