In-vivo MR spectroscopy (MRS) is a valuable method to obtain the biochemical status of normal and diseased tissues. Malignant tissues contain high concentration of choline containing compounds that can be used as a biochemical marker.

FUNDAMENTALS OF MR SPECTROSCOPY . John R. Hesselink, MD, FACR . MR spectroscopy provides a measure of brain chemistry. The most common nuclei that are used are 1 H (proton), 23 Na (sodium), 31 P (phosphorus). Proton spectroscopy is easier to perform and provides much higher signal-to-noise than either sodium or phosphorus.

= Nuclear Magnetic Resonance Basic Principles Spectroscopic technique, thus relies on the interaction between material and electromagnetic radiation The nuclei of all atoms possess a nuclear quantum number, I. (I 0, always multiples of .) Only nuclei with spin number (I) >0 can absorb/emit electromagnetic radiation. Chapter 13: Nuclear Magnetic Resonance (NMR) Spectroscopy direct observation of the H’s and C’s of a molecules Nuclei are positively charged and spin on an axis; they create a tiny magnetic field + + Not all nuclei are suitable for NMR. 1H and 13C are the most important NMR active nuclei in organic chemistry Natural Abundance 1H 99.9% 13C 1.1% used in Nuclear Magnetic Resonance spectroscopy. 2. NMR theory (13.3-13.5) A. All nuclei with unpaired protons or neutrons are magnetically active- they have a magnetic field arising from the unpaired nuclear particle. Of greatest interest to an organic chemist is hydrogen (including deuterium) and carbon ( the 13C isotope not the 12C isotope Magnetic resonance (MR) proton spectroscopy is a technique which mainly provides biological information regarding cellularity, energy, neuron viability, necrosis and ischemia. MR spectroscopy is ideal to assess the limits of brain tumors when planning surgery.
