Quantitative Susceptibility Mapping of Magnetic Quadrupole Moments

Figure 6

The field contribution by the quadrupole moment in subject 1 with in the z direction. To investigate the quadrupole moment contribution quantitatively, the quadrupole moment field contribution in our dipole + quadrupole model (red) was compared with anisotropy susceptibility field in dipole tensor model (blue). The field maps in a brain slice (left) and the histogram of each field contribution for whole brain (right) were shown.
