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 to measure hepatic triglyceride content: prevalence of hepatic steatosis in the general population.

American Journal of Physiology. Endocrinology and Metabolism, 2005
Despite the increasing prevalence of nonalcoholic fatty liver disease (NAFLD), the criteria used to diagnose the disorder remain poorly defined. Localized proton magnetic resonance spectroscopy (MRS) accurately measures hepatic triglyceride content (HTGC)

Magnetic Resonance Spectroscopy

Epilepsia, 1996
Summary: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

2023
Magnetic 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

2008
Magnetic 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, 1995
Magnetic 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, 1989
MRS 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 ...
