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 ...

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).

Nuclear magnetic resonance spectroscopy

1986
Nuclear 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 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.

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

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 imaging and spectroscopy

Current Opinion in Neurology, 1996
In the past year, magnetic resonance has assumed an increasingly important role in the study of patients with epilepsy that now extends beyond its demonstration of neuroanatomy and neuropathology into the fields of neurochemistry, neurometabolism and neurophysiology.

MAGNETIC RESONANCE SPECTROSCOPY AND BREAST CANCER

ANZ Journal of Surgery, 1998
The magnetic resonance (MR) experiment involves the excitation of a nuclear spin system. After excitation the system returns to equilibrium and depending on the type of experiment, several types of phenomena can be measured providing chemical and/or spatial information. Different nuclei can be examined (e.g.
