Magnetic Resonance Spectroscopy
Journal of Neuro-Ophthalmology, 2005Magnetic resonance spectroscopy (MRS) complements magnetic resonance imaging (MRI) as a non-invasive means for the characterization of tissue. While MRI uses the signal from hydrogen protons to form anatomic images, proton MRS uses this information to determine the concentration of brain metabolites such as N-acetyl aspartate (NAA), choline (Cho ...

MAGNETIC RESONANCE SPECTROSCOPY
Neuroimaging Clinics of North America, 1995Magnetic resonance spectroscopy, like PET, allows cerebral function to be assessed neuro-anatomically. In addition to being noninvasive and not requiring ionizing radiation, this technique can be performed with equipment available at most medical centers.

Magnetic Resonance Spectroscopy
Clinics in Perinatology, 1991MRS is a noninvasive technique that does not use ionizing radiation and can be used to measure relative metabolite concentrations in human tissues and organs in vivo. Phosphorus MRS can be used to study energy metabolites and intracellular pH. The first neonatal applications were described in 1983 in a study of cerebral metabolism.

Magnetic resonance spectroscopy
Medical Physics, 2008The nuclear magnetic resonance phenomenon has given rise to both magnetic resonance imaging, which yields morphologic data, and magnetic resonance spectroscopy (MRS), which yields chemical data. In humans these data are derived principally from the resonances of the hydrogen nucleus in the low molecular weight compounds in the body.

Nuclear magnetic resonance spectroscopy
Analytical Chemistry, 1995The range of problems in clinical chemistry that can be addressed by MRS is wide. The number of applications reported in the literature is growing steadily, particularly since the study of the composition of physiological fluids and tissues, and the changes thereof in disease, are well suited to study by MRS.

Cardiac magnetic resonance spectroscopy
Biochemistry and Cell Biology, 1998The article reviews cardiac magnetic resonance spectroscopy (MRS) in Canada. 31P MRS has been used to study cardiac energetics and intracellular pH in hearts subjected to ischemia-reperfusion and to evaluate the effects of pharmacological interventions.

Proton magnetic resonance spectroscopy
Critical Reviews in Neurosurgery, 1999Proton magnetic resonance spectroscopy (MRS) permits in vivo determination of biochemical parameters within brain tissue, utilizing the same magnetic resonance (MR) scanner and head coil that are utilized for conventional MR imaging. This technology has been evolving and improving over the past decade, with most of the current published work based on ...

Nuclear magnetic resonance spectroscopy
Analytical Chemistry, 1988Nuclear magnetic resonance (NMR) spectroscopy is one of the most widely used instrumental methods, with applications ranging from the characterization of pure compounds by high-resolution NMR to the diagnosis of disease by magnetic resonance imaging (MRI).

Magnetic Resonance Spectroscopy
2014Magnetic resonance spectroscopy (MRS) measures the concentration of chemicals in the brain using conventional magnetic resonance imaging (MRI) scanners, thereby providing a “virtual biopsy” that is noninvasive, quantitative, and objective for the characterization of psychiatric disorders as well as other brain disorders.
