commercial MR scanners are generally only capable of spectroscopy using the signals from pro-tons. Therefore this paper is of limited scope, giving an overview of technical issues that are important to clinical proton MRS, discussing some common clinical MRS problems, and …

Magnetic resonance spectroscopy (MRS) is a noninvasive technique that is used to measure the concentrations of different metabolites within body tissue. The basic scientific principle of MRS is identical to that of magnetic resonance imaging (MRI), except that, instead of anatomical images, Magnetic resonance spectroscopy (MRS) is unproven and not medically necessary. There is a lack of evidence demonstrating that the use of MRS improves health outcomes such as increasing diagnosis rates, reducing the number of unnecessary biopsies, and improving care or treatment planning accuracy in patients 13.1: Principles of molecular spectroscopy: Electromagnetic radiation λ = distance of one wave ν = frequency: waves per unit time (sec-1, Hz) c = speed of light (3.0 x 108-m • sec1) h = Plank’s constant (6.63 x 10-34 J • sec) Electromagnetic radiation has the properties of a particle (photon) and a wave. organic molecule (ground state Clinical MR Spectroscopy: Techniques and Applications is an excellent, well-organized textbook introducing the reader to principles, physics, and practical clinical applications of MR spectroscopy (MRS). The five well-respected authors, from the United States and Italy, have written a book that can be used both by readers with no prior MRS Nuclear magnetic resonance spectroscopy (NMR) was first developed in 1946 by research groups at Stanford and M.I.T., in the USA. The radar technology developed during World War II made many of the electronic aspects of the NMR spectrometer possible.

Aetna considers magnetic resonance spectroscopy (MRS) (also known as NMR spectroscopy) experimental and investigational for the following indications (not an all-inclusive list) because there is a lack of evidence of its efficacy in the medical literature. Brain Magnetic resonance spectroscopy (MRS), also known as nuclear or proton magnetic resonance spectroscopy, is a refinement of MRI. Specialized hardware and software attached to standard MRI equipment produce a spectroscopic graph of biochemical metabolites at various points in tissue, rather than an anatomic or structural image.

Its use is no longer For some years now, Magnetic Resonance Spectroscopy (MRS) has been incorporated as an auxiliary method for diagnosis to complement the MRI and increase MR Spectroscopy: Truly Molecular.
