General information about magnetic resonance spectroscopy

Magnetic resonance spectroscopy is a diagnostic tool used to evaluate the biochemical changes in brain. This is primarily used in case of tumors.  This technique is used to compare the normal brain tissue chemical composition with that of abnormal tumor tissue chemical composition. This tool also finds applications in the detection in tissue changes for epilepsy and stroke.

Market trends for magnetic resonance spectroscopy

The Global Market For Magnetic Resonance Spectroscopy is expected to increase at a fair rate during the forecast period. The growing demand for developed tools in the pharmaceutical sector and the implementation of these developed tools in large number of institutions have been the market driving factors for the magnetic resonance spectroscopy market.  The increasing awareness in health has been successful in expanding the market industry for this.

Further details about magnetic resonance spectroscopy

This technique basically works by the exploitation of the magnetic properties of certain nuclei. Magnetic resonance spectroscopy can be performed by two methods, one being the single-voxel spectroscopy (SVS) and the other being multi-voxel spectroscopy. In SVS, a single sample volume is considered and a spectrum is obtained from that particular sample while in multiple-voxel spectroscopy, multiple voxels are taken in a single slab of tissue and spectra are obtained from these multiple voxels under consideration. SVS holds few advantages over multiple-voxel technique since it is a more robust technique and can provide a better signal-to-noise ratio. A disadvantage of SVS is that it can provide a single spectrum only. Multi-voxel spectroscopy provides benefits such as covering a larger area, elimination of sampling error to a certain extent. This weakens the signal-to-noise ratio significantly and takes a longer time to scan. MRS provides doctors and researchers biochemical information about the tissues present in human body.  MRS is used to obtain information about the degree of malignancy of the tumor.

Magnetic resonance spectroscopy is a technique which is used to obtain biochemical information of compounds which are present in human cells and tissues. Proton MRS is capable of detecting a few of the hundreds of metabolites present in the human brain because least multi-molar concentrations are required for the detection of these metabolites. The metabolites present in human brain which are mainly detected are creatine (Cr), lactate, choline (Cho), N-acetyl aspartate (NAA), glutamine and glutamate, myo-inositol, lipids, and the amino acids alanine and leucine.

Conclusion

Magnetic resonance spectroscopy has eased the diagnosis of brain complications to a fair extent. The works aimed towards introducing new techniques will continue and might bring even more efficient technologies but the technique of MRS has been successful in making its place in today’s market.
