Demonstration of increased myocardial lipid with postischemic dysfunction (“Myocardial Stunning”) by proton nuclear magnetic resonance spectroscopy

Proton Nuclear Magnetic Resonance Spectroscopy

Quantification of plasma lipoproteins by proton nuclear magnetic resonance spectroscopy.

A new analytical procedure for quantifying plasma lipoproteins by proton nuclear magnetic resonance (NMR) spectroscopy has been developed that potentially offers significant advantages over existing clinical methods used for assessing risk of coronary heart disease. Analysis of a single spectrum of a nonfasting plasma sample, acquired simply and rapidly at moderate magnetic field strength (250 ...

Assessment of Cerebellar Metabolites Levels in Athletes Compared to Non-Athlete by Proton Magnetic Resonance Spectroscopy

Background: Adaptability to exercise training can increase the plasticity of the brain, and whether this can be due to a beneficial change in the neurometabolites, is uncertain. The purpose of this study was to evaluate basal metabolic concentrations of cerebellum, including N-acetyl aspartate (NAA) and Cholin(Cho) in athletes and compare them with non-athlete subjects. Materials and Methods: I...

Magnetic resonance spectroscopy in myocardial disease.

31-phosphorous ((31)P) magnetic resonance spectroscopy (MRS) is a technique that allows the noninvasive characterization of the biochemical and metabolic state of the myocardium in vivo. MRS is a pure form of molecular imaging using magnetic resonance signals from nuclei with nuclear spin to assess cardiac metabolism without the need for external radioactive tracers. (31)P MRS provides informat...

Diagnosing inborn errors of lipid metabolism with proton nuclear magnetic resonance spectroscopy.

BACKGROUND Many severe diseases are caused by defects in lipid metabolism. As a result, patients often accumulate unusual lipids in their blood and tissues, and proper identification of these lipids is essential for correct diagnosis. In this study, we investigated the potential use of proton nuclear magnetic resonance (1H-NMR) spectroscopy to simultaneously identify and quantify (un)usual lipi...
