'Baseline' Problems in Very Short Echo-time Proton MR Spectroscopy of Low Molecular Weight Metabolites in the Brain.

Popis výsledku v původním jazyce

Accurate and reliable quantification of low molecular weight metabolites in short echo-time proton MR spectra of the brain is usually considerably complicated by an uncharacterized broad baseline extending over the whole frequency range of the metabolitesignals of interest. Several sequences providing pure MR spectra of cerebral metabolites were designed, computer analyzed and experimentally tested. In these sequences, precautions have been made to avoid baseline contributions due to experimental imperfections, and signals of low molecular weight metabolites were distinguished from those of macromolecules (lipids), which are substantial contributors to the broad baseline, by utilizing the differences between their T 1 relaxation times.
