Synopsis

This lecture introduces the basic principles of MR Spectroscopy. Concepts such as chemical shift, J-coupling, the ppm-unit of the frequency axis, basic acquisition requirements and spectral resolution are explained. Furthermore, the effects of relaxation and field strength on the MR spectrum are discussed.
