  • Absolute quantification
  • Abstract Magnetic resonance spectroscopy is now in widespread use, which with various
    tools of spectra analysis can provide concentrations of metabolites. The influence of
    metabolites on human physiology is greatly. Due to the tiny variation of the
    concentration in various metabolites, the analytic method used in the quantitative
    determination of the absolute concentrations of metabolites plays an important role in
    this research area.
    In this thesis we present an analysis tool for segmentation of white matter, gray
    matte and cerebrospinal fluid using region growing with spatial space, and provide
    manual interaction for exception handling in this subject. Then we use this tool to
    analyze different percentages of white matter and gray matter with the default
    parameter by LCModel and correct partial volume effect. The results show that the
    proposed tool can improve significantly the accuracy in absolute quantitative analysis
    of concentration.
