Magnetic resonance spectroscopy in AD

Neurology, 2001
Proton MR spectroscopy (MRS) studies have found both decreased N-acetylaspartate (NAA) and increased myo-inositol in the occipital, temporal, parietal, and frontal regions of patients with AD, even at the early stages of the disease. This diffuse NAA decline is independent of regional atrophy and probably reflects a decrease in neurocellular viability.

Nuclear magnetic resonance spectroscopy

Analytical Chemistry, 1995
The range of problems in clinical chemistry that can be addressed by MRS is wide. The number of applications reported in the literature is growing steadily, particularly since the study of the composition of physiological fluids and tissues, and the changes thereof in disease, are well suited to study by MRS.

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 ...

Cardiac magnetic resonance spectroscopy

Biochemistry and Cell Biology, 1998
The article reviews cardiac magnetic resonance spectroscopy (MRS) in Canada. 31P MRS has been used to study cardiac energetics and intracellular pH in hearts subjected to ischemia-reperfusion and to evaluate the effects of pharmacological interventions.

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 ...

Advances in Magnetic Resonance Spectroscopy

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, 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 in epilepsy

2012
Abstract Proton magnetic resonance spectroscopy ( 1 H-MRS) is a noninvasive method for detecting brain metabolites. This chapter focuses on techniques and applications of 1 H-MRS and phosphorus ( 31 P) magnetic resonance spectroscopy ( 31 P-MRS) in the diagnosis of the epilepsies.

Nuclear magnetic resonance spectroscopy

Analytical Chemistry, 1988
Nuclear magnetic resonance (NMR) spectroscopy is one of the most widely used instrumental methods, with applications ranging from the characterization of pure compounds by high-resolution NMR to the diagnosis of disease by magnetic resonance imaging (MRI).

Proton magnetic resonance spectroscopy

Critical Reviews in Neurosurgery, 1999
Proton magnetic resonance spectroscopy (MRS) permits in vivo determination of biochemical parameters within brain tissue, utilizing the same magnetic resonance (MR) scanner and head coil that are utilized for conventional MR imaging. This technology has been evolving and improving over the past decade, with most of the current published work based on ...
