Magnetic resonance spectroscopy is currently used as a diagnostic tool in current medicine and chemistry. E ective read o spectrum can give scien- tists in ormation concerning biochemical composition o researched tissue. Method is non-invasive technique which provides details o metabolic chang- es in selected tissues. Due to number o limitations, quality o data obtained in spectroscopy is very o ten insu icient and methods o preprocessing are introduced. Such approach can be reached by application o singular value decomposition on data arranged in Hankel matrix. HSVD method can be used inpreprocessingtechniquesandin urtheranalysiso metabolites.
