Longitudinal Changes During Aging Using Proton Magnetic Resonance Spectroscopy

Longitudinal changes in proton magnetic resonance spectroscopy in cerebral infarction.

BACKGROUND AND PURPOSE Proton magnetic resonance spectroscopy has revealed changes in lactate and N-acetyl-aspartate in acute cerebral infarction. However, the details of these drastic changes and subsequent chronic changes have not been clarified. The purpose of this study was to disclose longitudinal changes in spectra seen in proton magnetic resonance spectroscopy. METHODS Six patients wit...

Proton Nuclear Magnetic Resonance Spectroscopy

Brain Proton Magnetic Resonance Spectroscopy

Magnetic resonance (MR) spectroscopy is an analytical method used in chemistry that enables the identification and quantification of metabolites in samples. It differs from conventionalMR imaging in that spectra provide physiologic and chemical information instead of anatomy. MR spectroscopy and MR imaging have their origin in nuclear magnetic resonance (NMR). NMR was first described in 1946 si...

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...

Examining lactate in severe TBI using proton magnetic resonance spectroscopy.

PRIMARY OBJECTIVE Clinical management of acute traumatic brain injury (TBI) has emphasized identification of secondary mechanisms of pathophysiology. An important objective in this study is to use proton magnetic resonance spectroscopy (pMRS) to examine early metabolic disturbance due to TBI. RESEARCH DESIGN The current design is a case study with repeated measures. METHOD AND PROCEDURE Pro...
