Magnetic resonance spectroscopy (MRC) is a technique that uses magnetic fields and RF waves to determine the concentration of metabolites in living tissues. Accordingly, brain MRI often uses metabolites containing P, Na, K, C, N, F to evaluate the concentration of metabolites to obtain a spectrum with peaks corresponding to the concentration of substances in the surveyed area.

Brain magnetic resonance imaging (Spectrography) is an important technique in diagnosing and supporting intervention in the treatment of dementia in particular and many neurological diseases in general.
