(a1) and (a2) corrA for the magnitude-vs-susceptibility correlations with respect to TE = [0, 60] ms, two vasculatures of radii = 2 and 4 micron, and three voxel sizes (see legend); (b1) and (b2) corrP for the corresponding phase-vs-fieldmap correlations. It is shown that a long TE may increase corrA but decrease corrP, and that both corrA and corrP decrease as image resolution refines. It is reminded that corrA‚Ȇ1 implies mismatch and nonlinearity of the mapping.
