ABSTRACT
Magnetic resonance imaging (MRI) provides anatomic images and morphometric characterization of pathological conditions, whereas magnetic resonance spectroscopy (MRS) provides metabolite/biochemical information about biological tissues in vivo and it is noninvasive. MRS has been used clinically for more than two decades. Other than brain, this advanced diagnostic tool is mainly used in the investigation of the diseases of prostate gland, calf muscle, spinal cord, breast, and liver. The aim of this chapter is to review the role of MRS in quantifying various metabolites in these organs and describe how this information could be used in the diagnosis of certain diseases.
