Magnetic resonance spectroscopy of the brain
Clinica Chimica Acta, 1992Magnetic resonance spectroscopy of the living brain is described. It is based on the same physics as magnetic resonance imaging, but instead of images based on the signal from tissue water, it measures specific compounds in the brain, currently numbering some two dozen.

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.

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
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
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 of the Heart
Cardiology Clinics, 1989MRS has clearly established itself as an important investigative tool for the study of cardiac metabolism and energetics. In animal models, it can provide insight into basic metabolic processes in both health and disease. Its nondestructive nature and capacity for serial measurements in the same system have given scientists the ability to monitor ...

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.

Magnetic resonance spectroscopy in neonates
Current Opinion in Neurology, 1995Magnetic resonance spectroscopy allows noninvasive assessment of cerebral metabolism in newborn infants. 31P magnetic resonance spectroscopy has demonstrated that birth asphyxia leads to delayed impairment of cerebral energy metabolism and 1H magnetic resonance spectroscopy has shown lactate accumulation and a later decline in N-acetyl aspartate ...

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).
