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...

proton magnetic resonance spectroscopy and cognitive impairment in patients with ischemic white matter lesions

background: the purpose of this study is to investigate the relationship between the cognitive impairment and naa/cr and cho/cr ratios in the proton magnetic resonance spectroscopy (1hmrs), and to assess the importance of 1hmrs in the early diagnosis of cognitive impairment in patients with ischemic white matter lesions (wmls). materials and methods: a total of 45 patients (23males and 22 femal...
