Magnetic Resonance Spectroscopy (MRS)
Magnetic resonance spectroscopy allows noninvasive and in vivo exploration of the molecular composition of tissue. It identifies certain molecular constituents - the metabolites - involved in physiological or pathological processes. Even though spectroscopy can be performed on different nuclei, we will focus here on the spectroscopy of the hydrogen nucleus, by far the most widely studied in clinical MRI.
