Recently, the multi-pole based (p-space) susceptibility
tensor imaging (STI) that only requires single gradient
echo MR scan was developed and was successful to produce
a tensor image of mouse brain at 7T, which was
strikingly correspondence to diffusion tensor image. In
this study, we compared the multi-pole based STI at 3T
and 7T in a human brain, and explored the T2* dependence
of the susceptibility anisotropy as well as the k-space
truncation effects caused by shifts of k-space .
