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.

Magnetic Resonance Spectroscopy
Epilepsia, 1996Summary:Magnetic resonance spectroscopy (MRS) is noninvasive and may be readily combined with magnetic resonance imaging (MRI). Attention has focussed on proton (1H) and phosphorus (31P) MRS, and studies have been undertaken by using single voxels or many voxels simultaneously (chemical‐shift imaging, magnetic resonance spectroscopic imaging).

Nuclear magnetic resonance spectroscopy
1986Nuclear magnetic resonance (NMR) spectroscopy is usually combined with infrared (IR) spectroscopy for the complete analysis of the structure of an unknown molecule. IR spectroscopy is used to detect a functional group in the sample, whereas NMR spectroscopy detects number of atoms and their type in sample.

Magnetic Resonance Spectroscopy
2023Magnetic resonance spectroscopy (MRS) is a completely noninvasive technique which allows the detection of brain metabolites’ concentrations in vivo. Brain metabolites are involved in energy processes, neuronal and membrane health, and in neurotransmission. The possibility of identifying changes in their concentration may open the way to early diagnosis

Microcoil nuclear magnetic resonance spectroscopy
Journal of Pharmaceutical and Biomedical Analysis, 2005In comparison with most analytical chemistry techniques, nuclear magnetic resonance has an intrinsically low sensitivity, and many potential applications are therefore precluded by the limited available quantity of certain types of sample. In recent years, there has been a trend, both commercial and academic, towards miniaturization of the receiver ...

[Brain magnetic resonance spectroscopy].
Journal de radiologie, 2007MR spectroscopy (MRS) sequences allow noninvasive exploration of brain metabolism during a MRI examination. Their day-to-day use in a clinical setting has recently been improved by simple programming of sequences and automated quantification of metabolites.

Magnetic Resonance Spectroscopy
2007Magnetic resonance imaging (MRI) is the current standard neuroimaging modality for patients with high-grade gliomas (HGG). A valuable addition to the morphologic information obtained from MRI is magnetic resonance spectroscopy (MRS), which provides information regarding the metabolic status of the brain and tumor.

Magnetic Resonance Spectroscopy
2020Magnetic resonance spectroscopy (MRS) is an established, non-invasive imaging technique for quantifying regional tissue biochemistry. It forms a valuable technique for the research and clinical evaluation of various neurological diseases. This chapter introduces the modality, describes typically evaluated metabolites, outlines evidence-based clinical ...

Magnetic resonance spectroscopy
2003Abstract The most useful and immediate impact of magnetic resonance in medicine has undoubtedly been the ability to display images of living systems (MRI) but some scientists are more excited about an alternative avenue of research-the non invasive study of biochemistry within the human body.
