Magnetic resonance spectroscopy of the human brain.
Magnetic resonance (MR; synonymous with NMR = nuclear magnetic resonance) is a universal physical technique best known for non-invasive detection and anatomical mapping of water protons (H). MR-spectroscopy (MRS) records protons from tissue chemicals other than water, intrinsic phosphorus containing metabolites, sodium, potassium, carbon, nitrogen, and fluorine. MRS is therefore an imaging tech...
متن کاملMagnetic resonance spectroscopy of the brain.
Magnetic resonance spectroscopy of the living brain is described. It is based on the same physics as magnetic resonance imaging, but instead of images based on the signal from tissue water, it measures specific compounds in the brain, currently numbering some two dozen. Being almost entirely non-invasive, it is well-suited for longitudinal and human studies of both normal function and disease p...
متن کاملBrain Proton Magnetic Resonance Spectroscopy
Magnetic resonance (MR) spectroscopy is an analytical method used in chemistry that enables the identification and quantification of metabolites in samples. It differs from conventionalMR imaging in that spectra provide physiologic and chemical information instead of anatomy. MR spectroscopy and MR imaging have their origin in nuclear magnetic resonance (NMR). NMR was first described in 1946 si...
متن کاملMagnetic Resonance Spectroscopy in the Brain
Standard clinical MR images depend on magnetic resonance signals of hydrogen nuclei, which are present in very high concentrations in water and, to a lesser extent in lipids. Although other hydrogen-containing metabolites are present, their concentrations are too low to contribute significantly to the MR signal unless the water signal is suppressed. This can be achieved using a chemical-selecti...
متن کاملMultivoxel magnetic resonance spectroscopy of brain tumors.
Magnetic resonance spectroscopy (MRS) is becoming more widely available for clinical applications and is able to provide information about the metabolic properties of regions of normal and abnormal tissue morphology. A critical question for the clinical management of patients with brain tumors is whether multivoxel MRS is able to add new information to the high-quality anatomical data provided ...
