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.

Advances in Magnetic Resonance Spectroscopy [PDF]
PET Clinics, 2013 Magnetic resonance spectroscopy (MRS) is a noninvasive technique that provides in vivo information about tissue metabolism. This article briefly describes the physical mechanisms of this powerful technique that enables imaging of endogenous markers for disease.

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).

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

Magnetic Resonance Imaging and Spectroscopy
2008Magnetic resonance imaging (MRI) and spectroscopy (MRS) are noninvasive techniques that allow the characterization of morphology, physiology and metabolism in vivo. MRI and MRS have become techniques of choice in many pre-clinical and clinical applications.

Magnetic resonance spectroscopy of the brain [PDF]
Postgraduate Medical Journal, 2012 Abstract Proton magnetic resonance (MR) spectroscopy of the brain is a non-invasive, in vivo technique that allows investigation into regional chemical environments. Its complementary use with MR imaging sequences provides valuable insights into brain tumour characteristics, progression and response to treatment.

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 ...

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 ...

Magnetic Resonance Spectroscopy in Migraine
Cephalalgia, 199531-phosphorus Magnetic Resonance Spectroscopy (MRS) is a technique developed for the non-invasive study of energy metabolism in living subjects. It determines the concentrations of high and low energy phosphates in resting and activated conditions, and of intracellular pH.

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 ...
