Imaging using nuclear magnetic resonance (NMR) was first demonstrated in the 1970s, and has since seen huge application in diagnostic radiology. It has been described using a number of formalisms and at a number of levels of complexity. This chapter traverses a path inbetween unnecessary rigorous complexity and over-simplifying inaccuracy of NMR imaging, and involves a discussion of most imaging experiments that can be understood using the principles of classical physics and quantum effects. It illustrates that NMR has a long history in helping to elucidate the chemical composition of samples via an analysis of their NMR spectra. The chapter emphasizes the concepts of spatial understanding and k- space, discusses Fourier imaging and studies nuclei namely hydrogen, phosphorus and carbon in the case of biomedical magnetic resonance spectroscopy.

Keywords: nuclear magnetic resonance; quantum effects; k- space; magnetic resonance spectroscopy; diagnostic radiology; NMR spectra
