P 101 Quantitative Chemical Shift Spectroscopy (CSI) with respect to B0- and B1-inhomogeneities

CSI is a method to visualize brain metabolism of, which may be important in the diagnosis of diseases like Alzheimer, dementia, brain tumors etc. Despite the fact that signal strength increases linearly with higher B0-fields, there exist many confounding variables, which diminish the accuracy of quantitative measurements of a 3T-device in relation to 1.5T.Susceptibility artifacts caused by inhomogeneities in the B0- and B1-fields as well as digitalization artifacts represent a challenging obstacle to measure accurate quantitative values of metabolite concentrations in CSI.
