Introduction in Magnetic Resonance Spectroscopy
- Penev, G. Georgieva-Kosarova, M. Al-Amin
Magnetic resonance spectroscopy (MRS) is an analytical method used initially in the field of chemistry. The methodology allows the identification and quantification of metabolites in different tissues and anatomical sites. It differs from conventional (MRI) in that the spectra provide physiological and chemical information, while conventional MRI provide structural (morphological) information. Both techniques (MRS and MRI) have their origin in nuclear
magnetic resonance (NMR). MRI was first described in 1946 by both Nobel Prize winners Edward Purcell of Harvard and Felix Bloch of Stanford University. MR spectrum can be obtained from different nuclei. Protons (1H) are the most used cores for clinical studies of human brain mainly due to its high sensitivity and abundance in brain tissue.
