Spectroscopy and Spectroscopic Imaging: In Vivo Chemical Assays by Exploiting the Chemical Shift
Spectroscopy (magnetic resonance spectroscopy; MRS) is often viewed (and marketed) as an advanced application of MRI. It is usually an add-on module that must be purchased from the manufacturer. This viewpoint is a strange one, as NMR was originally used for spectroscopy, and it was only after several “add-ons” that NMR spectrometers came to be used for imaging. Very-high-field research instruments designed for spectroscopy of homogeneous solutions held in test tubes are in fact sold with options to upgrade them for imaging of very small animals such as mice.
