Abstract :
The difference between the experimental and theoretical spatial response function (SRF) of a narrow tube with water is used for a localization test for Magnetic Resonance Spectroscopic Imaging (MRSI). From this difference a quantitative performance parameter is derived for the relative amount of signal within a limited region in the field of view. The total signal loss by the MRSI experiment and eddy currents is described by a parameter SL derived from the signal intensities of two echoes. Results of a European multi-centre trial show that this approach is suited for assessment of MRSI localization performance.
