Magnetic Resonance Spectroscopy
1998The electronic and vibronic states investigated so far were obtained from the Schrodinger equation where the Hamiltonian included only electronic and lattice contributions. Whether the atoms on the lattice sites have a magnetic moment or not was irrelevant since the latter does not contribute to the total energy of the system.

[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 imaging and spectroscopy
Current Opinion in Neurology, 1996In 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.

Elasto-magnetic resonance spectroscopy [PDF]
Europhysics Letters (EPL), 1996 A method of detecting and imaging elastic waves and some of the fundamental visco-elastic properties of the matter by MR was analysed. The detection of the phase changes in the transverse magnetization component enables the spectroscopic analysis of absorption, scattering and emission of the elastic waves in the matter. This implies that the method can

Magnetic resonance spectroscopy in epilepsy
2012Abstract 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.

Magnetic Resonance Spectroscopy
1990Information about intracellular metabolites and pH can be obtained directly and non-invasively from human tissues in vivo by using 31P magnetic resonance spectroscopy. These data can be used in the diagnosis of inherited metabolic conditions which result in abnormal cellular energetics.

Magnetic Resonance Spectroscopy
1992Magnetic resonance imaging for the diagnosis of tumors of the head and neck is characterized by high sensitivity but sometimes low specificity. Therefore great expectations have been raised by the development of high-resolution in vivo magnetic resonance spectroscopy (MRS). While MRI is based on the proton density and the relaxation times of the tissue
