Magnetic Resonance Spectroscopy: Physical Principles

Chapter

Abstract

Whereas MR imaging provides mainly anatomical information, magnetic resonance spectroscopy (MRS) is a method to obtain biochemical information about tissue. In this chapter, the basics of MRS such as chemical shift and J-coupling as well as contrast mechanism will be discussed and strategies for quantitation will be explained. This is followed by an introduction of the main metabolites that are detectable on today’s MR systems using widely available acquisition methods. Thereafter, the reader is given an overview of the standard acquisition techniques that are available on most scanners. Finally, practical suggestions are given on how to acquire high-quality study, considering signal-to-noise, where to measure, and which method to choose.
